摘要

摘要研究了二次谐波产生效率对温度的依赖关系，研究了聚酰胺酸携带两个端对端连接的DR1和DANS发色团的极化和弛豫动力学。我们用非线性光学发色团和主链等结构组分的自由体积模型和热取向波动来解释实验结果。

Poling and Relaxation Dynamics of a Nonlinear Optical Polyimide: Temperature-Dependent SHG Study

Abstract The temperature dependence of second harmonic generation efficiency have been studied to investigate the poling and relaxation dynamics of polyamic acid carrying two end-on attached chromophores of DR1 and DANS. We interpreted the experimental results with the free volume model and thermal orientation fluctuation of structural components such as the nonlinear optical chromophores and main chains.
