Abstract:

Novel photo and thermal dual-responsive inverse opal films were fabricated based on a crosslinked liquid crystal polymer (CLCP) containing azobenzene. Accompanying the deformation of the CLCP, switchable behavior on the reflection spectra of the inverse opal film was induced by light or temperature. We found that the optical properties were drastically decreased by thermal or photoinduced phase transitions of the CLCP. It was also found that the extent of decrease in the heat-induced inverse opal film is much more than in the one induced by light.

本研究以含偶氮苯的交联液晶聚合物（CLCP）为基础，制备了一种新型的双响应反蛋白石。反蛋白石薄膜在紫外-可见光的交替照射或温度的作用下，由于孔洞结构的改变，在反射光谱上表现出可切换的行为。这种在周期性结构中的变化是由偶氮苯的光化学反应引发的CLCP收缩或热诱导相转变所致。这是第一次用含偶氮苯的CLCP制备反蛋白石薄膜，并在薄膜的反射检测光谱上实现了可重复的光开关行为，可以方便地操作和控制。这项工作将拓宽含偶氮苯CLCP的实际应用。
