Synthesis and Study of Spectroscopic Properties of 5-(1-Oxido-3-pyridyl)-10,15,20-triphenyl Porphyrin and Its Zn(Ⅱ) Complex

Two novel sensitizers with pyridine-N-oxide zinc porphyrin and its zinc porphyrin as the anchor group and electron acceptor have been synthesized. The structures have been characterized by UV, elemental analyses and ~1H NMR. UV and fluorescence spectra show that they have good light absorbing properties in the range of visible light and suggest that they have potential applications in dye-sensitized solar cells.

Synthesis and Crystal Structure of Ag2（admtrz）2（CF3CO2）2（admtrz=4—amino—3,5—dimethyl—1,2,4—triazole）

1 INTRODUCTION Transition metal complexes bridged by 1, 2, 4-triazole group can produce interesting structures and specific properties[1]. Many attempts have been made to synthesize a variety of complexes with paramagnetic centers by using such ligands, and their structures and magnetic properties have been characterized[2]. However, the polynuclear Ag(I) complexes bridged by 1, 2, 4-triazole have been poorly studied[3]. Recently, we have prepared a series of silver(I) triazole complex…     

A Three-dimensional Self-penetrating Co(Ⅱ) Coordination Polymer Containing a 2D → 3D Parallelly Polycatenated Subnet

Hydrothermal assembly of Co~(2+) ion, a bis-imidazole ligand BIMB(BIMB = 1,4-bis(imidazol-1-yl)benzene) and a rigid bidentate linker 2,6-naphthalenedicarboxylic acid(H_2ndc), yields a novel three-dimensional(3D) self-penetrating coordination polymer {[Co(BIMB)(ndc)]·H_2O}_n(1). Complex 1 exhibits {6~5.8} topology and contains a 2D → 3D parallel polycatenated substructure. In addition, solid-state UV-vis absorption spectra of 1 were also investigated.

The crystal structure shows the copper(Ⅱ) atom is six-coordinated by two triazole nitrogen atom and four carboxylate group oxygen atom from four distinct L- ligand, thereby forming a 2D network structure. The cyclic voltammetric behavior of the complex was described.     

A NOTE ON AN INTEGRATED CAUCHY FUNCTIONAL EQUATION

In characterizing the semistable law, Shimizu reduced the problem to solving the equationH(x)=integral from n=1 to∞(H(x y)d(μ-ν)(y), x≥0) where μ andτ are given positive measures on [0,∞). In thisnote, we obtain a simple proof and show that some of his conditions can be weakened.
