电光高分子研究进展

Progress in Electro-optic Polymers

电光高分子是二阶非线性光学材料的重要组成部分,目前的研究重点主要在于合成具有高二阶非线性光学效应和取向稳定性以及低光学损耗的电光高分子,以满足高性能光学器件的制作要求。最近,电光高分子的设计与合成已经取得了很大的进展,例如结合"位分离"原理,利用高分子良好的加工性,获得了一些具有较好综合性能的高分子,可以较为有效地将小分子发色团的高β值转换为高分子大的宏观电光效应。本文综述了近几年来电光高分子的研究进展,主要包括线型电光高分子、树枝状电光高分子和超支化高分子。

Electro-optic(EO) polymers have play an important role in second-order non-linear optical materials.Nowadays,the study mainly focus on synthesizing EO polymers with large NLO effects,high thermal stability of the dipole moment after poling and low optical loss to fit the requirements of high-performance EO apparatus.Recently,according to the site isolation principle,great progress has been made on the design and synthesis of the EO polymers,which can translate the high hyperpolarizability(β) of the organic ...
