摘要: 在AM1和ZINDO方法基础上,按完全态求和公式编制了计算分子二阶非线性光学系数βijk的程序,并对偶氮系列分子的二阶非线性光学性质进行系统的理论研究,即在的基础上,在苯环左端引入不同的推电子基团,在其右端引入不同的吸电子基团,研究取代基变化时β变化的规律性,并在微观上给予解释。最后设计出非线性光学系数较大的分子。

Abstract: On the basis of AM1 and INDO/CImethods, we devise the program for the calculation of nonlinear second-order optical susceptibilities βijk and perform systematic theoreticalstudies on the nonlinear optical second-order properties of azobenzene series molecules ,i.e.on the basis of ,we induced different donors on the left sideof phenyl ring, and different acceptors on the right side of phenyl ring,and examined therule of β variation.The regularity summarized from the calculated results has been explainedmicromechanically.Finally,a molecule having a big nonlinear second-order optical susceptibility has been designed.
