Keggin结构钨磷酸/聚乙烯吡咯烷酮复合膜的制备和光致变色性质研究
Preparation and Photochromic Properties of Keggin Type Tungstophosphate Acids Based on Polyvinyl Pyrrolidone
摘要
Abstract
A new photochromic complex of Keggin type tungstophosphate acid/polyvinyl pyrrolidone system was prepared, and its thin films was made by the dipping method. Their photochromic properties were investigated by FTIR, UV-Vis spectra. The salts were formed by the combination of the ion based on the N atoms in the polymeric molecules and H+ of the acids. The UV-Vis spectra showed that this type of system had an excellent photochromic behavior. The g values of ESR spectra for the one-electron blues were the characteristic of tetragonal W(Ⅴ) complex in colored thin film. It was indicated that the charge could be transferred between the anion and cation under irradiation of UV light and the result in the oxidation of the cation and the reduction of the anion.关键词
