摘　　要：圆偏振发光材料具有特殊的旋光性,在光电器件、信息安全、3D显示等领域具有广阔的应用前景.传统的圆偏振发光材料一般存在发光不对称因子较低、合成复杂、可加工性不足等问题,在实际应用中严重受限.作为一种准一维光子晶体,胆甾相液晶具有周期性螺旋结构和手性放大功能,为提高圆偏振发光材料的不对称因子提供了可能.本文系统介绍了本课题组基于手性液晶材料构筑的一系列高性能圆偏振发光结构体系及其在信息交互领域的应用探索.Circularly polarized luminescence(CPL) materials—offering unique optical rotation—have the potential for photoelectronic devices, information security, 3D displays, and more. Traditional CPL materials are limited to practice owing to their low luminescence asymmetry factors, complex synthesis, and lack of processability. As a typical quasione-dimensional photonic crystal, cholesteric liquid crystal possesses a periodic helical structure and chiral amplification function, providing an effective route to enhance the luminescence asymmetry factor of CPL materials.In this paper, we systematically introduce the synthesis and information interaction applications of high-performing chiral liquid crystal-based CPL materials.
