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-optical polymers are an important part of the second-order nonlinear optical materials. The current research focuses mainly on the synthesis of electro-optical polymers with high second-order nonlinear optical effects and orientation stability as well as low optical loss to meet the needs of high-performance optical devices Claim. Recently, great progress has been made in the design and synthesis of electro-optic polymers. For example, in combination with the principle of “bit separation”, it is possible to obtain polymers with better overall performance by utilizing the good processability of the polymer and can be more effective The high β value of small molecule chromophores is converted into macromolecule macroscopic electro-optic effect. This review summarizes the research progress of electro-optic polymers in recent years, including linear electro-optical polymers, dendritic electro-optical polymers and hyperbranched polymers.
