Abstract

By introducing enantiomerically pure mono-bidentate N-donor ligands (LR/LS) into Yb(btfa)3(H2O)2 and Yb(dbm)3(H2O), respectively, two pairs of chiral YbIII enantiomers, namely Yb(btfa)3LR/Yb(btfa)3LS (D-1/L-1) and [Yb(dbm)3LR]·[Yb(dbm)3(C2H5OH)]/[Yb(dbm)3LS]·[Yb(dbm)3(C2H5OH)] (D-2/L-2) were isolated, where btfa− = 3-benzoyl-1,1,1-trifluoroacetonate, dbm− = dibenzoylmethanate, and LR/LS = (−)/(+)-4,5-pinenepyridyl-2-pyrazine. D-1/L-1 possess mononuclear structures in which the YbIII ions are eight-coordinated, while D-2/L-2 show cocrystal structures containing Yb(dbm)3(LR/LS) and Yb(dbm)3(C2H5OH) moieties in which the two YbIII ions are eight and seven-coordinated, respectively. They not only feature different molecular structures but also present distinct linear and nonlinear optical performances. Chiral mononuclear D-1 has better near infrared photo-luminescence (NIR-PL) and circularly polarized luminescence (CPL) performances than chiral cocrystal D-2. More remarkably, D-1/L-1 show large second-harmonic generation (SHG) responses (up to 1.25/1.28 × KDP) 18/16 times those of D-2/L-2 (0.07/0.08 × KDP). In addition, D-2/L-2 represent the first examples of lanthanide cocrystal complexes with NIR-PL, NIR-CPL and SHG properties. [ABSTRACT FROM AUTHOR]

Abstract

By employing enantiomerically pure mono-bidentate N-donors (LR/LS) as chiral bridging ligands to react with Cu(ClO4)2(H2O)6 in CH3CN–DMF mixed solvent, respectively, a pair of ionic one-dimensional (1D) Cu(II) chain enantiomers formulated as {[CuLR(CH3CN)(DMF)H2O](ClO4)2}n/{[CuLS(CH3CN)(DMF)H2O](ClO4)2}n (D-1/L-1) were isolated and structurally characterized, where LR/LS = (−)/(+)-4,5-pinenepyridyl-2-pyrazine. They crystallize in the noncentrosymmetric (NCS) P212121 space group of an orthorhombic system due to the introduction of chiral LR/LS, and the ClO4− groups as counteranions reside in crystal lattices, thus leading to charge separation with large dipole moments in their molecular structures. Based on crystal samples, investigation on their nonlinear optical (NLO) behaviors showed that D-1 and L-1 display simultaneously much larger second- and third-harmonic generation (SHG and THG) responses than their analogues based on the same chiral N-donors (LR/LS) and Cu(NO3)2(H2O)3 with NO3− acting as the coordination group to bind Cu(II) ions. The SHG intensities of D-1/L-1 are 0.62/0.60 × KDP (KH2PO4), and THG intensities of D-1/L-1 are 238/228 × α-SiO2. Our finding indicates that coordination polymers (CPs) with charge separation and NCS structures, i.e., ionic CPs with NCS arrangements are the ideal NLO crystalline materials for the simultaneous observation of large SHG and THG responses, thus providing a new approach to obtain NLO-active CP crystalline materials with high-performance SHG and THG responses.

Abstract

This paper described the synthesis of meso/macroporous phosphotungstic acid (HPW) /TiO2 catalyst with quaternary ammonium bromide and monodispersed polystyrene spheres (PS) as dual-template. The synthetic parameters, such as concentration of the templates and the alky chain length of quaternary ammonium bromide was studied carefully and optimized to generate catalyst with regulated porous features. The chemical properties of the catalyst was also investigated, X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) measurements confirmed the Keggin-type HPW were highly dispersed on the TiO2 framework. The optimal meso/macroporous HPW/TiO2 catalyst exhibited excellent catalytic activity in the oxidation of refractory sulphur compounds such as benzothiophene (BT), dibenzothiophene (DBT), and 4,6-dimethyldibenzothiophene (4,6-DMDBT). DBT was removed within 2 h at 30 °C under selected reaction conditions and the apparent activation energy for DBT oxidation was calculated to be 45.7 kJ/mol. The high ODS reaction rate of catalyst could be attributed to the combination of unique meso/macroporous architecture allowing for efficient mass transport of reactants and products in pore channel and its high surface area, large mesoporous size, and pore volume enabling sufficient exposure of catalytic active sites. Moreover, the meso/macroporous HPW/TiO2 catalyst also exhibited excellent reusability with no obviously degradation even after eight cycles.
