摘要
报道了针对二维卟啉类有机分子材料的光学非线性性质研究，讨论了几种非对称配置电负性分子团对构成分子的光学非线性的影响，表明配置的分子基团电负性越大，合成分子的非线性超极化率越大。实验研究了这些分子的光学非线性响应特性，分析了各种非线性机制在分子非线性响应中的作用。
The third-order nonlinear optical properties of several porphyrin-like metal complexes have been measured by degenerate four-wave mixing at 1. 06 μm with 40 ps pulses. Both the magnitude and dynamics of the nonlinear response are measured, with each system exhibiting the different responses owing to the influence of charge negativityof substituted clusters. Analysis is given for the micromechanism of nonlinearresponses.
