Abstract

TiO2 photoelectrodes modified with organic dyes with pyridine anchoring groups are prepared, which are used as photoanodes of dye-sensitized photoelectrochemical cells for efficient water reduction with high photocurrent density and stability in aqueous solutions. Vigorous H2 generation with a production rate of around 250 μmol h−1 is realized with a photoanode of an active area of 5 × 5 cm2. [ABSTRACT FROM AUTHOR]

12. Trisubstituted alkenes with a single activator as dipolarophiles in a highly diastereo- and enantioselective [3+2] cycloaddition with vinyl epoxides under Pd-catalysis.

Abstract

1,1,2-Trisubstituted alkenes with a single strongly electronic withdrawing activator, which are unreactive electron-deficient alkenes in transition metal-catalyzed [3+2] cycloaddition with vinyl three-membered heterocycles, were used in the Pd-catalyzed asymmetric cycloaddition of vinyl epoxides, affording multifunctionalized tetrahydrofurans in high yields with high diastereo- and enantioselectivities.

14. Resistive memory devices based on a triphenylamine-decorated non-precious cobalt(ii) bis-terpyridine complex.

Author

Tang, Jian-Hong, Sun, Tian-Ge, Shao, Jiang-Yang, Gong, Zhong-Liang, and Zhong, Yu-Wu

Subjects
METAL complexes, TRIPHENYLAMINE, COBALT compounds
Abstract

The ITO/active material/Au sandwiched devices of a cobalt(ii) bis-terpyridine complex decorated with two triphenylamine motifs display appealing flash-type resistive switching with a large ON/OFF ratio (＞103) and low operating voltages (＜±3 V). In contrast, devices with the triphenylamine-appended terpyridine ligand show WORM-type memory behaviour. [ABSTRACT FROM AUTHOR]

Abstract

Organic-inorganic mixed-valence systems with strongly-coupled triarylamine and cyclometalated osmium have been developed. They display two well-separated redox couples at low potentials. Each of the three readily accessible oxidation states can be distinguished by the absorbance at three different wavelengths.

17. Shape and phase evolution from CsPbBr3 perovskite nanocubes to tetragonal CsPb2Br5 nanosheets with an indirect bandgap.

Abstract

Tetragonal CsPb2Br5 nanosheets were obtained by an oriented attachment of orthorhombic CsPbBr3 nanocubes, involving a lateral shape evolution from octagonal to square. Meanwhile, the experimental results, together with DFT simulation results, indicated that the tetragonal CsPb2Br5 is an indirect bandgap semiconductor that is PL-inactive with a bandgap of 2.979 eV.

Abstract

Ceramic membranes were fabricated by in situ synthesis of alumina nanofibres in the pores of an alumina support as a separation layer, and exhibited a high permeation selectivity for bovine serum albumin relative to bovine hemoglobin (over 60 times) and can effectively retain DNA molecules at high fluxes.
