Advancing circularly polarized luminescence materials for practice
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 quasi-one-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.
