exposure. The ultimate stability of the poled polymers was directly related to the number of crosslinking substituents that were attached to the chromophore pendant group. With two reactive groups per chromophore significant SHG was retained at temperatures above the initial polymer glass transition temperature. © 2014 Wiley Periodicals, Inc. J. Polym.

基于第二谐波产生(S
HG)的热稳定性,合成,极化和评估了一系列带有超极化侧链发色团的可光交联聚合物。光引发可以控制固化的开始。通过红外光谱监测交联,并通过在曝光期间施加缓慢的温度上升来实现最佳转化。极性聚合物的最终稳定性直接与发色团侧基相连的交联取代基的数量有关。每个生色团具有两个反应性基团,在高于初始聚合物
玻璃化转变温度的温度下保留了显着的S
