Four AIO-structured cuprous iodide hybrids were synthesized, with modifying the tail atoms of ligand. They all show strong luminescence, stable and good solution processability. They can be applied as rare-earth element-free lighting phosphors.

Identification and control of the central adrenal vein (CAV) are key steps in laparoscopic adrenalectomy. However, the retroperitoneal laparoscopic left adrenalectomy (RLLA) lacks identifiable anatomical landmarks and does not have advantage of quickly exposing CAV. Here, we developed surgical maneuver and tactics of using the inferior phrenic vein (IPV) as a landmark in RLLA. During operations, we searched for the IPV between superior margin of renal artery and anterior aspect of psoas major muscle, and then the left IPV was followed and applied as an anatomical landmark to identify the CAV. Moreover, our study showed that variations in the left adrenal venous anatomy occurred in cases with pheochromocytomas. The application of left IPV as a landmark to search for CAV has important clinical significance in RLLA.

Two metal–organic frameworks, [Zn(BTA)2]n (LMOF-1), [Zn3(BTA)2(5-tbuip)2]n (LMOF-2) (BTA = 1H-benzotriazole, 5-tbuip = 5-tert-butylisophthalic acid) have been solvothermally synthesized. They show strong blue luminescence and LMOF-1 shows unusually detecting behavior to Ag+.

Three anionic luminescent metal-organic frameworks (LMOFs; [M(tcbpe)(CH3)2NH2]·H2O; M = In3+, Eu3+, Gd3+; tcbpe = 4',4‴,4‴″,4‴‴'-(ethene-1,1,2,2-tetrayl)tetrakis[(1,1'-biphenyl)-4-carboxylic acid]) are synthesized by employing the tetraphenylethene core ligand H4tcbpe with M3+ ions. They stack in the similarly 4-fold-interpenetrated three-dimensional porous structure. All give blue emission when excited at 365 nm, with fluorescence quantum yields of 34.8% (MOF-In), 7.1% (MOF-Eu), and 28.1% (MOF-Gd). Somewhat surprisingly, these three complexes are extremely stable both in various solvents and across a broad pH range: MOF-In is stable between pH = 0 and 14, and MOF-Eu and MOF-Gd are stable between pH = 0 and 13. Additionally, they also show good proton conductivities of 2.29 × 10-5 S·cm-1 (MOF-In), 2.02 × 10-4 S·cm-1 (MOF-Eu), and 1.24 × 10-4 S·cm-1 (MOF-Gd) at high temperature under 98% relative humidity. To the best of our knowledge, this is the first reported LMOF series combining aggregation-induced emission behavior with good proton conductivities.

Herein, we report the synthesis of two new manganese-based luminescent metal-organic frameworks (LMOFs) [Mn0.5(tipe)(1,4-ndc)] n (1) and [Mn(tipe)(1,4-ndc) (H2O)·(DMF)2·(H2O)3] n (2) [tipe = 1,1,2,2-tetrakis(4-(1H-imidazol-1-yl)phenyl)ethene (tipe) and 1,4-ndc = 1,4-naphthalenedicarboxylic acid] constructed from an aggregation-induced emission (AIE) chromophore ligand. Compound 1 can undergo a facile single-crystal-to-single-crystal transformation to form compound 2, which results in an increase in dimensionality from a two-dimensional (2D) network to a three-dimensional (3D) network. Both compounds demonstrate excellent performance for the solution-phase detection of Fe3+ ions through a significant and rapid quench in luminescence emission. Fluorescence titration experiments reveal that compound 2 is more selective toward Fe3+ compared to compound 1 because of its 3D stacking mode. The Ksv value for compound 2 (32 378 M-1) is twice as large as that for compound 1 (15 854 M-1) for the detection of Fe3+ ions. We attribute this significant increase in performance to the increase in dimensionality. In addition, compound 2 demonstrates high selectivity and sensitivity for the detection of Cr3+ cations and Cr2O72- anions.

Three new luminescent metal–organic frameworks (LMOFs), [Zn(tppa)(ndc)]n (1), [Cd(tppa)(oba)]n (2), [Zn2(tppa)(bpdc)2]n (3) (tppa = tri(4-pyridylphenyl)amine, ndc = 1,4-naphthalenedicarboxylic acid, oba = 4,4′-oxydibenzoic acid, bpdc = 4,4′-biphenyldicarboxylic acid) have been synthesized by solvothermal method. Complexes 1 and 2 are 2-D two-fold interpenetrating structures, aligning into a 3-D structure through C–H⋯π stacking interactions, while 3 is a 5-fold interpenetrating three-dimensional structure. The internal quantum yields (IQYs) of complexes 1–3 are 32.7%, 45.7% and 24.0% (λex = 365 nm), separately. Furthermore, all the complexes show different luminescence signal changes towards aromatic volatile organic compounds (AVOCs). Complex 1 exhibits a high sensitivity in the detection of both Fe3+ and Cr3+ with large quenching coefficients of Ksv 2.57 × 104 M−1 and 2.96 × 104 M−1, respectively. All these results demonstrated potential applications in chemical sensing.

Two new title MOFs, namely [Cd2(TIPA)2(bpodc)2]n (1 or MOF-1), [Cd2(TIPA)2(oba)2]n (2 or MOF-2) (TIPA = tris(4-(1H-imidazol-1-yl)phenyl)amine, bpodc = benzophenone-4,4′-dicarboxylic acid, oba = 4,4′-oxydibenzoic acid), have been synthesized via a solvothermal method. MOF-1 and MOF-2 both have a 2-fold interpenetrating 3D framework, and the calculation of PLATON display that porosity are 18.6% and 19.5%, respectively. Attributing to MOF-2's uncoordinated carboxylate groups, it exhibits a high sensitivity in detecting Fe3+ with a very large quenching coefficient Ksv up to 27 027 M−1. Moreover, MOF-2 also has potential applications in chemical sensing of CrO42− and Cr2O72−.

A very stable ZnII-organic framework, {[Zn(Titpe)0.5(bpodc)]·(H2O)3}n (1, Titpe = 1,1,2,2-tetrakis(4-(imidazol-1-yl)phenyl)ethane, bpodc = benzophenone-4,4-dicarboxylic acid), has been synthesized under hydrothermal conditions. Single-crystal X-ray analysis reveals that 1 crystallizes in the monoclinic system and P21/c space group. Its overall structure is a 3-D stacking with a porosity of 20.95% and a 4-c type topological network; it shows good stability in many solvents. Studies of the solution-phase detection of metal cations show that Fe3+ and Cr3+ ions can quench luminescent emission of 1. Fluorescence titration experiments show that 1 is more selective to Fe3+ (Ksv = 2.8 × 104 M−1) than Cr3+ (Ksv = 1.4 × 103 M−1). The solution-phase detection for anions by 1 also show high selectivity and sensitivity for Cr2O72– anions (Ksv = 1.2 × 104 M−1). With water stability and strong blue luminescence, 1 can potentially apply as a reversible multi-responsive luminescence sensor for Fe3+, Cr3+, and Cr2O72– in aqueous solutions.

A new three-dimensional luminescent cobalt (II) metal–organic framework, [Co(Titpe)(bcpf)·(DMF)]·(H2O)2·(DMF) (compound 1, JUST-8) (Titpe = 1,1,2,2-tetrakis(4-(1H-imidazol-1-yl)phenyl)ethane, bcpf = 4,4′-sulfonyldibenzoic acid; DMF = N, N-dimethylformamide), has been solvothermally synthesized by using CoCl2·6H2O and a mixture of ligands: Titpe ligand and bcpf ligand. Single crystal X-ray analysis reveals that 1 crystallizes in the triclinic system and [Formula: see text] space group with a = 13.2097(14) Å, b = 13.9519(14) Å, c = 14.4413(15) Å, α = 89.949(7)°, β = 70.303(7)°, γ = 80.322(7)°, V = 2465.7(5) Å3, Z = 2, Mr =1032.97, Dc = 1.391 g/cm3, μ = 0.455 mm−1, F(000) = 1070, R = 0.0585, and wR = 0.1540 for 8674 observed reflections ( I > 2σ( I)). Its overall structure is a double-fold interpenetrated framework, and it shows a porosity of 12.97% based on a calculation by PLATON and a 4- c type topological network with the point symbol of {6^5.8}. The Co atom bridges the Titpe ligands to form the one-dimensional chains into a two-dimensional layered structure and then connects the auxiliary ligands to get a three-dimensional structure. Compound 1 showed a blue fluorescence emission with the peak maximum at 431 nm (λex = 314 nm).

Background. The effect of lipoprotein(a) (Lp(a)) on prostate cancer (PCa) is unclear. The aim of this study was to investigate the association between serum Lp(a) levels and clinicopathological features in patients with PCa. Methods. A total of 376 consecutive pathologically diagnosed PCa patients were enrolled and were classified as a low-intermediate-risk group or a high-risk group. The association of Lp(a) and the other lipid parameters including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), TC/HDL-C, LDL-C/HDL-C, and remnant cholesterol (RC) with clinicopathological parameters was tested by univariate and multivariate logistic regression analyses. Results. The high-risk PCa patients tended to have higher Lp(a) levels (p=0.022) while there was no significant difference regarding the other lipid parameters (p>0.05) compared to low-intermediate-risk counterparts. Patients with PSA≥100 ng/ml had significantly higher Lp(a) levels than subjects with PSA<100 ng/ml (p=0.002). Univariate logistic regression analyses revealed that high Lp(a) levels were correlated with high-risk PCa (Q4 vs. Q1, HR=2.687, 95% CI: 1.113-6.491, p=0.028), while the other lipid parameters were not correlated with high-risk PCa. In the stepwise multivariate regression analysis, the association between Lp(a) levels and high-risk PCa remained significant (Q4 vs. Q1,HR=2.890, 95% CI: 1.148-7.274, p=0.024) after adjusting for confounding factors including age, body mass index, hypertension, diabetes, coronary artery disease, and lipid-lowering drugs. Conclusions. This is the first study showing the positive association between high Lp(a) and adverse clinicopathological features of PCa. PCa patients with high Lp(a) tends to be more aggressive and should receive more attention in clinical practice.

Although vinyl azide is an important class of functional group that possesses diverse reactivities and is a convenient synthon for N-heterocycles, cyclic vinyl azide remains underdeveloped due to difficult preparation. This work discloses a rhodium catalyzed intramolecular [4 + 2] cycloaddition reaction that can afford challenging fused bicyclic vinyl azides efficiently in ambient conditions and paves a facile route for the research in the chemistry of cyclic vinyl azides.

Objective. It has been well elucidated that multiple types of cancers are at high risk of thrombosis. Several studies have indicated the prognostic value of fibrinogen (Fib) and D-dimer (DD) in prostate cancer (PCa). However, it remains unclear regarding the association of the comprehensive coagulation markers with the clinicopathological features of PCa. Methods. A total of 423 pathologically diagnosed patients with PCa were consecutively collected and stratified as low-intermediate-risk or high-risk groups. The association of coagulation parameters including Fib, DD, prothrombin (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and antithrombin III (AT-III) with clinicopathological features was determined by univariate and multivariate logistic regression analyses. Results. The levels of Fib, DD, and PT were significantly higher in the high-risk group ( p < 0.001 , p < 0.001 , and p = 0.043 , resp.), while APTT, TT, and AT-III were similar between two groups ( p > 0.05 , all). Univariate logistic regression analysis demonstrated that Fib, DD, and PT were all positively correlated with high-risk PCa ( OR = 2.041 , p < 0.001 ; OR = 1.003 , p < 0.001 ; OR = 1.247 , p = 0.044 ). Nonetheless, after adjusting for PSA, grade, and stage, Fib (T3 vs. T1, OR = 15.202 , 95% CI: 1.725-133.959, p = 0.014 ) but not DD or PT was the unique independent factor associated with high-risk PCa in the multivariate regression analysis. Conclusions. Our study firstly revealed that Fib but other coagulation markers was independently associated with the severity of PCa, suggesting Fib might be useful in PCa risk stratification beyond PSA, stage, and grade.

Background The clinical significance of left inferior phrenic vein (IPV) during left retroperitoneal laparoscopic adrenalectomy (RLA) for adrenal tumors is unclear. We aimed to investigate the surgical feasibility and value of IPV as a landmark during RLA. Methods Between September 2016 and November 2018, 92 consecutive left RLAs were performed by the same surgeon. All the operations were performed through the approach of three relative avascular planes༎Then we searched for IPV between superior margin of renal artery and anterior aspect of psoas major muscle. The left IPV was used as an anatomical landmark to identify and ligate the central adrenal vein (CAV). Results All 92 operations were performed successfully with one conversion to open surgery. We identified the CAV following left IPV in all cases. The left IPV drained into the CAV in 100% of cases, and variant venous anatomy (2 CAVs) was encountered in 2 pheochromocytoma cases (2.17%). Peritoneum perforation occurred in one case in operation (1.09%). Postoperative complications (fever) occurred in 3 patients (3.26%). The mean operative time was 75.82 ± 21.55 minutes༎The average postoperative hospital stay was 3.57 ± 0.76 days༎Pathological examination revealed: cortical adenoma in 72 cases (78.26%), adrenal cyst in 11 cases (11.96%), pheochromocytoma in 6 cases (6.52%), cortical hyperplasia in 1 case (1.09%), medullary hyperplasia in 1 case (1.09%), and hemangioma in 1 case (1.09%). Conclusions Using left IPV as a landmark to search for and handle CAV has important clinical significance in left RLA.

Stabilizing metal nanoparticles (MNPs) with metal–organic frameworks (MOFs) has become a favorable pathway for developing efficient hybrid photocatalysts, while effective charge transfer within hybrid catalysts is largely elusive. In this work, we employed a semiconductor-like Zr-MOF, NH2-UiO-68, with an amino-functionalized linker and permanent porosity enabling the confinement of guest species for the first time. Pt NPs have been embedded inside (referred to as Pt@MOF), outside (referred to as Pt/MOF) or both inside and outside (referred to as Pt-MOF) of the flowerlike NH2-UiO-68 by varying synthetic methods and Pt NP amounts. Among these different hybrids, the 2 wt% Pt@NH2-UiO-68 sample presents the highest photocatalytic CO2 reduction activity under visible light irradiation, and is far superior to the 2 wt% Pt/NH2-UiO-68, 1 wt% Pt@NH2-UiO-68, and 4 wt% Pt-NH2-UiO-68 samples. The appropriate location and content of Pt NPs in the catalysts would facilitate the contact between Pt NPs and NH2-UiO-68, which is beneficial to form Pt-MOF heterojunctions, thereby achieving efficient charge transfer in the photocatalytic process. More importantly, effective charge transfer from NH2-UiO-68 to the excited Pt NPs via Pt-MOF Schottky junctions can accordingly inhibit the recombination of photogenerated charge carriers, ultimately leading to the enhancement of photocatalytic activity.

The luminescent complexes [Cd(BIMP)2(NDC)2]n and [Zn(BIMP)2(NDC)]n (where (3-BIMP) = 3-(1H-benzoimidazol-2-yl)pyridin-2(1H)-one and NDC = 2,6-naphthalenedicarboxylic acid) have been synthesised under hydrothermal conditions and their crystal structures determined. [Cd(BIMP)2(NDC)2]n exhibited a 1D → 2D → 3D framework structure and [Zn(BIMP)2(NDC)]n has a 3D porous structure. Under the same excitation energy (λex = 389 nm), [Zn(BIMP)2(NDC)]n showed a stronger fluorescence emission than the free 3-BIMP ligand, the NDC ligand and [Cd(BIMP)2(NDC)2]n.

Three new luminescent metal–organic frameworks (LMOFs) based on d10 metals (Zn2+, Cd2+) and the highly emissive aggregation-induced emission ligand 1,1,2,2-tetrakis(4-(4-carboxyphenyl)phenyl)ethene(H4tcbpe) are reported, with the formulas [Cd3(tcbpe)1.5(DMF)(H2O)2]·(DMF)6·(C2H5OH)3 (1), [Zn(tcbpe)(DMF)]·(MeCN) (2), and [Cd(tcbpe)]·(MeCN) (3). Compounds 1 and 2 both emit strong green light with internal quantum yields (IQYs) as high as 66.8% and 65.7%, respectively, while compound 3 emits bluish green light with 37.2% IQY. A solution-phase sensing study shows that 1 has the highest sensitivity to nitroaromatic compounds and demonstrates that it is potentially useful as a luminescence-based chemical sensor. Density functional theory calculations are used to explain the sensing mechanism and relative sensitivity of compound 1 to various nitroaromatic compounds.

A new 3D luminescent Zinc (II) metal-organic framework, has been solvothermally synthesized by using Zn(NO3)2⋅4H2O and a mixture of ligands: Titpe ligand and bcpf ligand. The molecular formula is [Zn(Titpe)(bcpf)•(DMF)]n, (Compound 1, Titpe = 1,1,2,2-tetrakis(4-(1H-imidazol-1-yl)phenyl)ethane, bcpf= 4,4΄-sulfonyldibenzoic acid). Compound 1 crystallizes in the triclinic system, space group P -1, with a=12.9990(9), b=14.2181(10), c=14.3781(10) A, α = 89.974(4)°, β = 71.640(4)°, γ = 80.732(4)°, V = 2485.6(3) A3, Z = 2, Mr = 1039.43, Dc =1.389 g/cm3, μ = 0.600 mm−1, F(000) = 1076.0, R = 0.0747 and wR =0.2508 for 9724 observed reflections (I > 2σ(I)). Topology analysis shows that compound 1 is a double interpenetrating structure. In addition, due to the ligand-to-ligand charge transfer of the TPE chromophore, luminescent spectra of 1 shows that it emits strong blue light. Compound 1 can detect Fe3+ ions with high selectivity and sensitivity among diverse inorganic cations in aqueous solution and is also a highly selective sensing material for CrO42− and Cr2O72- ions.

Background: Monocarboxylate transporter isoform 1 (MCT1) is an important molecule in mediating lactate transportation. Recent studies have shown an oncogenic role of MCT1 in cancer development. Methods: In this study, we aimed to investigate the expression and role of MCT1 in bladder cancer (BCa). MCT1 expression was detected in 124 BCa tissues and their clinicopathological significance was analyzed. We also used The Cancer Genome Atlas database to explore the prognostic association of MCT1 with BCa. Cell proliferation, migration and invasion assays were performed on BCa cells in which MCT1 was downregulated. The effect of MCT1 on BCa cell aerobic glycolysis, as well as its association with HIF-1α, was tested. Results: We found that high MCT1 expression correlated with lymph node and distant metastasis. Patients with high-MCT1 expression showed shorter overall survival than those with low-MCT1 expression. Knockdown of MCT1 inhibited BCa cell proliferation, migration and invasion, and affected expression of epithelial-mesenchymal transition related proteins. Downregulation of MCT1 decreased lactate levels in cell medium, as well as HK2, GLUT1 and LDHB expression. In addition, MCT1 expression was partly dependent on HIF-1α. Conclusions: Taken together, our study has shown a prognostic role of MCT1 in BCa, and provided potential diagnostic and therapeutic options for BCa patients.

A series of 10-substituted-3,3,6,6-tetramethyl-9-aryl-3,4,6,7,9,10-hexahydroacridine-1,8(2H,5 H)-dione derivatives 2 were synthesized by reaction of compounds 1 with amines. The compounds 1 were effectively prepared by 5,5-dimethylcyclohexane-1,3-dione and aldehydes in the presence of a little amount of L-proline as catalyst at room temperature. All the compounds were characterized by IR, MS, and 1H NMR. The crystal data of 1b and 2d were collected by X-ray single-crystal diffraction, and compounds 2b and 2d exhibited better inhibitory activity against HepG2 cells.

This study was performed to identify the prognostic impact of lymphovascular invasion (LVI) in patients with upper urinary tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). A systematic search in PubMed, Embase, and the Cochrane Library was performed to identify relevant studies. The outcomes of interest, including progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS), were extracted, and the pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were used for effect size estimation. Subgroup, metaregression, and sensitivity analyses were performed to explore potential origins of heterogeneity. Publication bias was estimated by Egger’s linear regression and funnel plot. Our meta-analysis included a total of 27 studies involving 17,453 patients. The pooled HRs were statistically significant for PFS (HR=1.73, 95%CI=1.41–2.11), CSS (HR=1.87, 95%CI=1.54–2.27), and OS (HR=1.56, 95%CI=1.29–1.87), with high heterogeneity (I2=77.8%, 70.3%, and 59.2%, respectively). Four studies explored the prognostic value of LVI in patients with advanced tumor stages (T3–T4). The fixed effects model (I2=33.9%) showed that the pooled HR was 1.64 (95%CI=1.35–1.99) for CSS. Egger’s plots showed no significant publication bias (PFS: P=0.443, CSS: P=0.096, and OS: P=0.894). Our meta-analysis demonstrated that LVI is a poor prognostic factor for UTUC and is strongly associated with disease recurrence, cancer-specific mortality, and overall mortality.

BACKGROUND There are few studies that address how to quickly locate the renal vein after processing the renal artery during retroperitoneal laparoscopic radical nephrectomy (RLRN) for renal cell carcinoma (RCC). This study aimed to evaluate the feasibility of an easy and effective method to locate the renal vein in RLRN. MATERIAL AND METHODS Between September 2016 and October 2017, a total of 44 consecutive cases of RLRN were performed. All the surgeries used the proposed study method to locate the renal vein, in which surgeons located the renal artery following the medial arcuate ligament on the posterior abdominal wall, then the surgeon directly searched for the renal vein caudally relative to renal artery when performing left nephrectomy, but cranially when performing right nephrectomy. RESULTS Among the 44 enrolled RLRN patients, there were 28 left nephrectomies and 16 right nephrectomies. We found the renal vein in most cases successfully by our proposed method. The renal vein was located caudally relative to the renal artery in 27 cases of the left kidney (96.4%), and was located cranially in 14 cases of the right kidney (87.5%). The mean operative time was 135.0±27.8 minutes. No intraoperative complications occurred. Postoperative complications (fever) developed in 5 patients. Pathological examination revealed: clear cell carcinoma in 34 cases (77.3%), chromophobe renal cell carcinoma (RCC) in 5 cases (11.4%), papillary RCC in 3 cases (6.8%), multilocular cystic RCC in 1 case (2.3%), and oxyphil cell adenoma in 1 case (2.3%). CONCLUSIONS Our proposed method to search for the renal vein might be a safe and feasible procedure to accelerate the process of handling the renal pedicle and of great practical significance in RLRN surgery.

To master the prevention knowledge and behavior of echinococcosis and the influencing factors in residents in agricultural and pastoral areas of Maerkang City, so as to provide the reference for formulating the policy and strategy of echinococcosis prevention and control.In April, 2017, 796 residents in agricultural and pastoral areas of Maerkang City were selected by the multi-stage stratified random sampling method, and surveyed with questionnaires. The main questions included the prevention knowledge and related behaviors of echinococcosis.The awareness rate of prevention knowledge of echinococcosis was 70.1% (558/796). The awareness rate was the lowest in the group aged 15 to 25 years. The difference of knowledge awareness rate was statistically significant among the different age groups (χThe awareness rate of echinococcosis prevention knowledge in Maerkang City should be improved. The health education should be focused on the young people, people with low educational level, and people who have dogs. The behaviors of drinking unboiled water, tying dogs, feeding dogs with anthelmintic regularly, and burying dog' s dung should be advocated.[

Six novel metal–organic-frameworks (MOFs), [Ni(nbpdc)(4,4′-bpy)(H2O)]n (1), [Ni2(nbpdc)2(4,4′-bpy)2(H2O)2]n (2), [Ni(nbpdc)(4,4′-bpy)]n (3), [Mn(nbpdc)(4,4′-bpy)]n (4), [Co(nbpdc)(4,4′-bpy)]n (5), and [Zn2(nbpdc)2(4,4′-bpy)]n (6), with different crystal structures and divalent cations (Zn(II), Ni(II), Mn(II), and Co(II)) from the same ligands nbpdc and 4,4′-bpy (H2nbpdc = 2,2′-dinitro-4,4′-biphenyldicarboxylic acid, 4,4′-bpy = 4,4′-bipyridine) have been synthesized and characterized. Complex 1 showed a new point group of 222 and a new topology structure of sqc6. Crystal structures of complexes 2–6 with the same nonpolar point group of 2/m were determined by single-crystal X-ray diffraction. Complex 2 exhibited a rare three-interlude 3D structure with (44·62)(48·66·8) topology. Complexes 3–5 featured the same topology structure of (44·610·8)(44·62). Complex 6 had a 3D framework with (10)(6·82·103·124)2(62·8)2(8)2 topology. In addition, complex 1 displayed commendable adsorption of N2 at room temperature. 4 and 5 showed antiferromagnetism. Moreover, all six MOFs displayed abnormal dielectric peaks from 225 K to 275 K, which were measured at various frequencies and temperatures.

A series of xanthene derivatives were prepared from cyclohexane-1,3-dione and aromatic aldehydes through Knoevenagel–Michael and cyclisation reactions in methanol:ethanol mixture (1:1), catalysed by a very small amount of l-proline at room temperature. Isomeric tetraketones were synthesised from dimedone and aromatic aldehydes under the same condition. Condensation of them with amines gave acridione derivatives. The crystal structure of an acridione was obtained and determined by X-ray single-crystal diffraction.
