【摘要】 在水或乙醇溶液中制备了钨磷酸与二甲胺、乙二胺、二乙胺、丙二胺、联吡啶、邻菲罗啉和六次甲基四胺形成的电荷转移盐，用元素分析、ＩＲ、ＵＶ对其进行了表征，结果表明，杂多酸形成电荷转移盐后，其阴离子的Ｋｅｇｇｉｎ结构基本不变，但其特征振动峰的位置随有机阳离子给电子能力的不同而发生不同程度的红移或蓝移，电荷转移盐溶于水后完全解离，所合成的部分电荷转移盐具有光致变色效应，在可见光下即可发生光激发电子转移，ＥＳＲ研究表明光激发电子转移处于单电子还原阶段．更多还原

【Abstract】 The charge-transfer salts were prepared in enthnol or aqueous solution from tumgstophosphate acid and diethylamine、dimethylamine、ethyleneddiamine、triethylamine、propylenediamne、dipyridine、1,10-phenanthloline、hexamethylenamine.They were characterized by elemnetal anaysis、IR and UV spectra.The results indicate that the struchure of anion has a little changing after the charge-transfer salts formed,but the characteristic vibrational band have some of red shift or blue shift relation to the release electron ability of the organic compounds.The charge-transfer salts were all disrupted after they wer solved in solution.A part of them have photochromism,the were take place the charge tranfer in the visible light.The study of ESR indicate that the charge transfer was in one-electron step更多还原
