gels. The gelators can be assembled to form a nanofiber physical gel network, which limits the movement of the liquid crystals and enhances the stability of the CPL properties. Meanwhile, liquid crystal physical gels show self-supporting ability and the gel–sol phase transition temperature can reach 136 °C. The amplification of the glum value is achieved by self-assembly of chiral liquid crystals, and
近年来,主客体掺杂CPL液晶材料的制备方法和性能调控取得了很大进展。但是,仍然存在一些基本问题有待解决,例如复杂的封装和不稳定的CPL特性。考虑到上述问题,本研究将凝胶剂引入到主客体掺杂的CPL液晶材料中,制备了CPL液晶物理凝胶。凝胶剂可以组装形成纳米纤维物理凝胶网络,从而限制液晶的运动并增强 CPL 性能的稳定性。同时,液晶物理凝胶表现出自支撑能力,凝胶-溶胶相变温度可达136℃。glum的放大值是通过手性液晶自组装实现的,g lum值可以达到-0.31。相结构随电场和温度的变化而变化,可以通过改变温度和电场来调节 CPL 的性质。随着施加电压或温度的增加,g lum值降低。因此,我们成功地制备了一种具有自支撑性能、刺激响应性能和大g lum值的新型CPL液晶物理凝胶。
