摘要: 在ZINDO方法基础上,按完全态求和(SOS)公式编制了计算分子二阶非线性光学系数βijk和βμ的程序,研究了对硝基二苯乙炔系列衍生物的结构和非线性光学性质,考察了分子共轭链长和给电子基团对βμ的影响.结果表明,对硝基二苯乙炔系列衍生物上连有推电子基团有利于增大二阶光学非线性,扩大共轭范围也有利于增大二阶光学非线性,但对透明性则影响不大.

关键词: 对硝基二苯乙炔系列衍生物, 二阶非线性光学系数, ZINDO-SOS

Abstract: On the basis 0f ZINDO methods, according to the sum-over-states expression, wedevised the program for the calculati0n of the nonlinear sec0nd-order optical susceptibilities,βijkand βμ of molecules, and studied the structures and nonlinear optical properties of p-nitrobis(phenylethynyl)benzene series derivatives.The influence of the molecular conjugatedchain lengths, and the donor to βμ.was examined.lt is concluded that the donor substitutedon p-nitr0 bis(phenylethynyl)benzene series derivatives facilitates the nonlinear second-orderoptical susceptibility.Extending the conjugated area, the nonlinear second-order optical sus-ceptibility increases too, but the transparency has not been greatly influenced.
