Hairy particles consisting of polyisoprene-b-polystyrene (PI-b-PS) were synthesized by polymerization-induced self-assembly (PISA) based on a living anionic polymerization method. The molecular agg...

Even without external photon pumping, cavity vacuum fields can be strongly coupled with molecular transitions (electronic excitation and molecular vibration), resulting in the formation of polarito...

An inverse opal structure was created using artificial melanin particles composed of a polystyrene core and a polydopamine shell as the template. The melanin-mimicking polydopamine that remained in...

Millimeter-sized polystyrene particles coated with a hydrophobic polypyrrole overlayer were successfully synthesized by aqueous chemical oxidative seeded polymerization. The dried particles could e...

Anionic polymerization of methacrylate-functionalized ionic monomers, 2-(methacryloyloxy)ethyltrimethylammonium chloride (MTAC) and 3-(N-2-methacryloyloxyethyl-N,N-dimethyl)ammonatopropanesulfonate...

The surface reorganization behavior of a crystalline ABCBA-type copolymer and a non-crystalline ABA-type copolymer including poly(2-methacryloyloxyethyl phosphorylcholine) was investigated. The crystalline domain in the block copolymer suppressed the surface reorganization when exposed to either hydrophilic or hydrophobic condition.

The steric structures of luminescent compounds play a key role in controlling the thermal and optical properties. In order to improve the thermal properties of a strong luminescent Eu(III) coordina...

Poly(3,4-ethylenedioxythiophene) (PEDOT) grains were synthesized by solvent-free chemical oxidative polymerization in one-step and one-pot manner. The resulting PEDOT grains had atypical shapes wit...

B,B-Dimesityl-substituted dithieno-1,2-dihydro-1,2-diborin was synthesized and its properties and reactivity were studied. Owing to the noticeably electron-deficient and antiaromatic character of the 1,2-dihydro-1,2-diborin ring, this compound was found to homolytically cleave diatomic hydrogen (H2) gas at ambient temperature under 1 atm to afford a hydrogen-bridged bis(borane). This reaction was accompanied by a dramatic color change from dark green to yellow in addition to a turn-on fluorescence response.

2-Methacryloyloxyethyl choline phosphate (MCP) was synthesized by a ring-opening reaction of cyclic phosphates with 2-(dimethylaminoethyl methacrylate). The crude MCP consisted of an endo-cyclic de...

We report here a synthetic route to unsymmetric cyano-substituted oligo(p-phenylene-vinylene)s (COPVs), which have not been reported so far. These molecules were synthesised in high yield through a...

A coumarin–imine–quinoxaline linkage designed based on the Strecker reaction selectively exhibits blue fluorescence on the addition of CN− to an imine moiety at neutral pH. The receptor facilitates rapid (within 5 min), selective, and sensitive (detection limit: 1.4 µM) detection of CN−.

The reactions of fluorinated ylide, generated from tris(dimethylamino)phosphine and tribromofluoromethane, with simple aldehydes and reactive ketones gave the expected Wittig reaction products. How...

The incorporation of fluoro-containing moieties into polymers can significantly change their surface properties. In this study, we synthesized two polyacrylates with different fluoro-containing sid...

Glycosylation reaction of 2,3-di-O-benzoyl-protected galactosyl donors with ethyl thioglucoside acceptor to prepare lactose derivatives was investigated. The presence of benzyl ether moieties at th...

In this paper, we show a simple biomimetic approach for fabricating thermally stable porous films with multilayered structures by mimicking beetle wings. Honeycomb-patterned porous films (honeycomb...

The vibrational dynamics of the CO stretching mode of 9-fluorenone (FL) in CD 3 CN and CD 3 0D were studied by subpicosecond UV-pump and IR-probe spectroscopy. We found that the CO stretching band is blue-shifted by hydrogen-bond formation in the S 1 state but red-shifted in the So state. In both CD 3 CN and CD 3 OD, the time evolution of the transient absorption spectrum was observed on a picosecond time scale, likely because of vibrational cooling and hydrogen-bond dynamics.

Reduction of formyl groups in natural chlorophyll (Chl) d purified from a cyanobacterium, Acaryochloris marina, and its demetalation product, pheophytin (Phe) d, was kinetically analyzed. Chl d exh...

We have successfully synthesized polymer nanoparticles which reflect precisely the size of monomer droplets formed by the tandem acoustic emulsification. This new synthetic method involves sequenti...

The title carbene generated by photolysis of the corresponding diazo compound at room temperature gave 4,6-di-tert-butyl-1,1-dimethyl-3-phenylindan quantitatively. Triplet states of the carbene were observed by laser flash photolysis of the diazo compound in the presence of benzophenone as a triplet sensitizer.

Rhenium(I) dinitrogen complex cis-ReH(N2)(PMe2Ph)4 catalyzes an aldol type reaction of ethyl cyanoacetate with benzaldehyde under moderate conditions. Rhenium enolate complexes Re(NCCRCO2R′)(NCCHRCO2R′)(PMe2Ph)4 (R = H, R′ = Me; R = H, R′ = Et; R = H, R′ = n-Bu; R = Me, R′ = Et) and Re(NCCHCO2Et)[NC(EtO2C)C=CHPh](PMe2Ph)4 as active intermediates of the aldol type reactions have been isolated.

Irradiation of 8-azatricyclo[3.2.1.02,4]oct-6-enes in dry ether with a low pressure mercury lamp gave azabishomobenzenes through [2π+2σ]-type migration reactions between C–N bonds and olefin moieties.
