推拉电子结构非线性光学偶氮苯衍生物的合成

Syntheses and characterization of nonlinear optical Azobenzene derivatives

有机非线性化合物的非线性光学效应主要来自非定域的π电子 ,与无机非线性光学材料相比 ,具有较高的非线性系数和具有可设计、合成使材料多样化等诸多优点。我们设计、合成了两大类八种具有D -π -A结构的偶氮化合物 ,对它们进行了结构表征。它们有较大的二阶非线性分子超极化率 。

Nonlinear optical organic compounds have more advantage than inorganic compounds. Based on the requirement of the second-order nonlinear optical molecular structure, series of the azobenzene molecules with D-π-A structure are synthesized. They are characterized by element analysis,IR and UV.
