Coordination complexes of copper(II) acetate, ammonia, aliphatic amines, and pyridine have been prepared. Molecular formulae on the basis of percentage of constituent elements were found to be Cu(OAc)2(am)2, where OAc represents acetate ion and am any amine used. Conductivity measurements in nitrobenzene and formamide indicate that the complexes are nonelectrolytes and thus it is suggested that acetate ions are also coordinated. Molecular weight measurements in the same solvents confirm this. Visible absorption measurements in formamide show a single band at about 635 mμ.

Abstract In this work, we systematically investigate the impacts of electron-donor based on Triphenylamine (TPA). The Geometry structure, energy levels, light-harvesting ability and ultraviolet-visible absorption spectra were calculated by using Density Functional Theory (DFT) and Time-Dependent-DFT. The electron injection rate of the TPA-N(CH3)2 based dyes has 0.71 eV for high among the dye sensitizer. The First and Second order Hyperpolarizability of the 11.95 × 10−30 e.s.u and 12195.54 a.u, respectively for TPA-N(CH3)2 based dye. The calculated absorption spectra were showed in the ultra-violet visible region for power conversion region. The study reveals that the electron transfer character of TPA-N(CH3)2 based dyes can be made suitable for applications in Dye-Sensitized Solar Cells.

This paper describes the synthesis of 5-amino-6-cyano-2-phenylthieno[ 2,3-d]oxazole and its utilization for the preparation of a range of azo disperse dyes. These aryl azo disperse dyes were applied on polyester fabric and their fastness properties were evaluated. The dyes were characterized by NMR and IR spectroscopy. The visible absorption spectra of these dyes were Recorded.
