二维卟啉类分子材料的三阶非线性光学性质的研究

Third-Order Optical Nonlinear Response in Asymmetric Pentaazadentate Porphyrin-like Metal Complexes

报道了针对二维卟啉类有机分子材料的光学非线性性质的研究，讨论了几种非对称配置电负性分子团对构成的分子的光学非线性的影响，表明配置的分子基团的电负性越大，合成的分子其非线性超极化率越大，通过实验研究了这些分子的光学非线性响应特性，并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. 06μm with 40ps 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 negativity of substituted clusters. Analysis is given for the micromechanism of nonlinear responses.
