手性诱导制备聚合物圆偏振发光材料研究进展

Circularly polarized luminescence (CPL) materials have become a research hotspot at the intersection of chiral optics and materials science， owing to their enormous application potential in cutting-edge fields such as 3D displays， information encryption， biosensing， and photodetection.Among them， polymer-based CPL materials combine high thermal stability， good processability， and excellent solubility， offering unique advantages in the fabrication of low-cost， solution-processable， large-area， and flexible chiral light-emitting devices.In recent years， chiral induction strategies， which facilitate the transfer of chiral information from an external environment or an inducer to achiral polymers through non-covalent interactions or purely physical interactions (such as selective absorption and reflection)， have emerged as simple and flexible method for constructing CPL materials.This paper systematically reviews the latest research progress in utilizing chiral induction strategies to fabricate polymer-based CPL materials.It focuses on discussing several different chiral induction mechanisms and the performance advantages of the resulting materials， while highlighting their applications in optoelectronic devices， biomedicine， and information security.Finally， the current challenges and future development prospects in this field are discussed and summarized.Keywords： circularly polarized luminescence； polymer； chiral induction； luminescence dissymmetry factor 文章编号： 1000
