通过对含氟丙烯酸酯-甲基乙烯基异氰酸酯共聚物进行官能化，制备了具有高玻璃化转变温度（Tg）的非线性光学乙烯基聚合物。提出了一种改进的噻吩桥联发色团的合成方法。极化膜的聚合物显示出相当高的和稳定的非线性光学响应，即使在高温下。本文合成了基于取代的二氰基亚甲基-二氢呋喃受体的噻吩桥联发色团。
Nonlinear optical vinyl polymers with high glass transition temperature (Tg) were prepared by the functionalization of a fluorinated acrylate-methyl vinyl isocyanate copolymer. A modified pathway to obtain a thiophene bridged chromophore was worked out. Poled films of the polymers show a fairly high and stable nonlinear optical response, even at elevated temperatures. The thiophene-bridged chromophore, based on a substituted dicyanomethylene-dihydrofuran acceptor, synthesized here.
