杂多酸电荷转移盐的制备、表征及非线性光学性质研究——H_3PMo_(12-n)W_nO_(40)·mH_2O和六次甲基四胺形成的电荷转移盐

Synthesis,Characterization and Nonlinear Optical Properties of a Series Charge Transfer Salts Based on H 3PMo 12-n W n O 40 ·m H 2O and Hexamethylenamine

以 Ｈ３ Ｐ Ｍｏ１２ － ｎ Ｗｎ Ｏ４０ ·ｍ Ｈ２ Ｏ 和六次甲基四胺为原料合成了一系列电荷转移盐，并用元素分析，红外光谱，电子光谱进行了表征．红外光谱和漫反射电子光谱研究表明在固体中阴离子和有机阳离子之间存在强的相互作用；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，化合物二阶倍频效应增强。

A series charge transfer salts were synthesized from H 3PMo 12-n W n O 40 ·m H 2O and hexamethylenamine,and characterized by elemental analysis,IR spectra and UV spectra.The result of elemental analysis indicates that there are two N atoms of the HMTA taking part in the forming of the charge transfer salts.The results of IR spectra and UV spectra prove that there is a strong interaction between anion and the organic cation in solid state.The results of the nonlinear optical property show that the SHG and thd χ (3) of the charge transfer salts increases with the rise of the tungsten in the molecules.
