为了减少发色团偶极相互作用,在二阶非线性发色团苯胺-吡咯啉分子的受体吡咯啉的N原子上分别接入三种不同的枝化基团,将其高μβ值有效转化为高电光性能.研究了三种枝化发色团的电光性能和相关化学物理性质,比较了不同枝化基团对发色团的综合性能的影响.结果表明,枝化基团的接入引起发色团分子的紫外吸收红移,枝化基团修饰的发色团,改善了苯胺-吡咯啉发色团分子与聚碳酸酯(APC)的相容性,并明显减少了发色团偶极静电相互作用,提高了发色团在电场下的极化效率,使其在聚碳酸酯(APC)薄膜中的极化序列参数可高达44%.并测得当枝化发色团在APC中掺杂的含量为9%时,聚合物体系电光系数高达75 pm/V(1315 nm激光测定).
In order to reduce the chromophore dipole interaction, three different branching groups were attached to the N atom of the acceptor pyrroline of the second-order nonlinear chromophore aniline-pyrroline molecule, respectively, to make their high μβ values effective The electro-optic properties and the related chemical and physical properties of the three branched chromophores were studied and the effects of different branched groups on the overall performance of the chromophore were compared.The results showed that the branching groups Into the chromophore molecules caused by UV absorption redshift, branched group modified chromophores to improve the aniline - pyrroline chromophore molecules and polycarbonate (APC) compatibility, and significantly reduce the hair color The results show that the polarimetric efficiency of the chromophore in the electric field can be increased up to 44% by the dipole electrostatic interaction, APC doped content of 9%, the polymer system of high electro-optical coefficient of 75 pm / V (1315 nm laser determination).
