摘　　要：合成了一系列由钨钼混配杂多酸H3PMo12 -nWnO4 0 ·mH2 O(n =0 ,1,3,9,11,12 )和 2 ,7-二甲基喹啉形成的分子组成为 [DMQH]3PMo12 -nWnO4 0 的电荷转移盐 ,并用元素分析 ,红外光谱 ,电子光谱进行了表征 ,结果显示在固体盐中阴离子和有机阳离子之间存在强的相互作用 ;光照下阴阳离子之间可以发生电荷转移 ,导致阳离子的氧化和阴离子的还原 ,非线性光学性质研究表明 ,随着化合物分子内钨取代数的增多 ,化合物倍频效应增强 ;三阶非线性系数增大 .A series charge trnasfer salts,[DMQH] 3PMo 12-n W nO 40 (n=0,1,3,9,11,12), were synthesized from H 3PMo 12-n W nO 40 ·mH 2O and 2,7_dimethylquinoline and characterized by elemental analysis, IR spectra and electronic spectra. The results indicate that there is a strong interaction between the cation and the anion in the solid state;the heteropoly blue will be produced after the samples are irradiated under light. The study of second and third order nonlinear optical indicate that the SHG and the third_order susceptibilities of the charge transfer salts are increased the increase of the tungsten number in the molecules.
