Abstract
A photo-invertible helical cholesteric superstructure was constructed by doping a novel chiral fluorescence photoswitch and a static dopant with opposite handedness into a nematic host. The handedness of circularly polarized luminescence can be reversibly inverted accompanied by a positive-negative change of luminescence dissymmetry factor values upon alternate light irradiations.
摘要
通过将一种新型手性荧光光开关和具有相反手性的静态掺杂剂掺杂到向列相主体中，构建了一种光可逆螺旋手性超结构。圆偏振发光的手性可以通过交替光照可逆反转，同时发光不对称因子值发生正负变化。
