Abstract

The effect of polymer matrices on the nonlinear-optical properties of composite materials with guest chromophores containing a divinylquinoxaline π-electronic bridge has been investigated. Poly(methyl methacrylate) and different methacrylic copolymers as well as epoxy-amine oligomers with azo chromophores in the backbone or as side groups have been used as polymer matrices. The use of a polymer matrix containing carboxylic groups has resulted in significant decrease in the nonlinear-optical coefficient d₃₃ as compared to the case of poly(methyl methacrylate) matrix with a guest chromophore content of 20 wt%. For materials with binary chromophores, d₃₃ values of the studied materials have been higher than for conventional composites.

聚合物基体对掺杂含二乙烯基喹喔啉π电子桥的发色团的复合材料非线性光学响应的​​影响

摘要

研究了聚合物基体对含二乙烯基喹喔啉π电子桥的客体发色团的复合材料非线性光学性质的影响。聚（甲基丙烯酸甲酯）和不同的甲基丙烯酸共聚物以及在主链上或作为侧基具有偶氮发色团的环氧-胺低聚物已被用作聚合物基质。与客体生色团含量为20重量％的聚（甲基丙烯酸甲酯）基体的情况相比，使用含有羧基的聚合物基体导致非线性光学系数d ₃₃显着降低。对于具有二元生色团的材料，d ₃₃ 所研究材料的值已高于常规复合材料。
