| 摘 要： | 有机铵十聚钨酸盐具有显著的光致变色性质,电子自旋共振研究表明光致变色是由于光照过程中有五价钨生成,发生了光还原反应。本文研究了二异丙胺和六氢吡啶十钨酸盐(分别简写为DIAW_(10)和PIPDW_(10)在溶液中的光致变色性质,考察了水、乙腈、二甲基甲酰胺(DMF)、二甲基亚砜(DMSO)对光致变色性质的影响,对比研究了四丁基铵盐(NBuW_(10))的情况,还测定了不同光照时间下W(V)浓度,可见吸收光谱和循环伏安,提出了光致变色性质与体系中所含活泼氢的定量关系,初步揭示有机铵十聚钨酸盐光致变色的本质。

| Abstract: | The photochromism of piperidine, diisopropylammonium and tetrabutylammonium decatungstates in different solvents(H2O, MeCN, DMF) has been studied with the determination of the W(V), CV and Vis-absorption spectra. The conclusion might be drawn that the photochromism is the result of interaction of the active hydrogen contained in system with the decatungstate radicles on exposure to light, and that there is a definite relationship between the W(V) and the active hydrogen. Mono-or double-electron reduced species have also been discussed. |
