A strategy was developed for regulating circularly polarized luminescence performance by increasing the order parameter value of achiral dichroic dye in cholesteric liquid crystal media without changing the helical superstructure. Additionally, the circularly polarized luminescence and fluorescence intensity response (contrast ratio) was also improved as the order parameter value increased under the DC electric field. Efficient encryption could be achieved by modulating the structure of achiral dichroic dyes in cholesteric liquid crystals.

通过胆甾型液晶定向有序参数调节非手性二色性染料介导的圆偏振发射

开发了一种通过增加胆甾型液晶介质中非手性二色性染料的有序参数值而不改变螺旋超结构来调节圆偏振发光性能的策略。此外，在直流电场下，随着有序参数值的增加，圆偏振发光和荧光强度响应（对比度）也得到改善。通过调节胆甾型液晶中非手性二色性染料的结构可以实现有效的加密。
