几种金属有机化合物的合成、结构和光学非线性

Synthesis, Structure and Optical Nonlinearity of Several Organometallic Compounds

采用相转移Ｗｉｔｉｇ反应合成了５种二茂铁金属有机化合物，对它们进行了红外光谱、紫外光谱、元素分析、核磁共振的表征，研究了分子的结构和二阶非线性光学性质。研究表明该类化合物具有较高的分子二阶非线性极化率，作为给体和受体的推拉电子取代基的存在和扩大共轭范围都对增大二阶光学非线性有利。

Five of ferrocenyl organometallic compounds have been synthesized with phase transfer Wittig reaction and characterized by IR, UV, elemental analysis and 1HNMR. The crystal X ray structure and nonlinear second order optical properties of the compounds have been studied. It is concluded that this kind of compounds have fairly large second order susceptibility, and that, both donor acceptor substitutes and the extending conjugated area facilitate the nonlinear second order optical susceptibility.
