Abstract

The present invention relates to a polycarbonate containing nonlinear optical chromophores, a synthesis method and an application thereof. According to the present invention, bischloroformate and nonlinear optical chromophores containing double hydroxyl groups are subjected to copolymerization so as to successfully introduce the nonlinear optical chromophore molecule into the polymer chain segment of the polycarbonate, and concurrently a bisphenol monomer is introduced to adjust the number of the nonlinear optical chromophore molecules in the chain segment so as to effectively prepare the suspension connection type polycarbonate electro-optic material containing a certain amount of the nonlinear optical chromophore molecules; after the polycarbonate containing the nonlinear optical chromophores is dissolved with an organic solvent and then is subjected to film coating, the maximum electro-optic coefficient of the prepared polarized electro-optic polymer film is 75 pm / V, wherein the prepared electro-optical material has a high glass transition temperature, such that the nonlinear optical chromophore molecules have good orientational stability in the material; and the polycarbonate containing the nonlinear optical chromophores has the following structure.

Description
