摘　　要：合成了由六次甲基四胺与Ｈ３ＰＭｏ１２Ｏ４０·ｎＨ２Ｏ，Ｈ４ＳｉＭｏ１２Ｏ４０·ｎＨ２Ｏ 和Ｈ４ＧｅＭｏ１２ Ｏ４０·ｎＨ２Ｏ 形成的具有二阶非线性光学性质的电荷转移盐，并由元素分析，红外光谱，电子光谱进行了表征。结果表明六次甲基四胺分子中有两个Ｎ 原子参与盐的形成，固体中阴阳离子之间存在强的相互作用；非线性光学性质研究表明，三种电荷转移盐的倍频效应分别为ＫＤＰ和０．０２ ，０ ．１１ 和０．０６ 倍。The charge transfer salts with second order nonlinear optical properties have been synthesized based on hexamethylenamine and the heteropoly acids,H 3PMo 12 O 40 ·nH 2O,H 4SiMo 12 O 40 ·nH 2O and H 4GeMo 12 O 40 ·nH 2O and characterized by elemental analysis,IR spectra and UV spectra.The results indicate that there are two N atoms of the HMTA taking part in the formation of the charge transfer salts.There is a strong interacton between the cation and the anion.The results of the second order nonlinear optical properties show that the SHG of the three kinds of charge transfer salts are 0.02,0.11 and 0.06 times for KDP respectively.
