摘要:

圆偏振发光(Circularly polarized Luminescence, CPL)材料在三维显示、 信息加密以及生物成像等领域展现出广阔的应用前景, 近年来备受关注. 其中, 发光不对称因子(glum)是衡量CPL材料的关键参数. 如何有效地提升glum, 不仅是当前研究的核心问题之一, 也是推动CPL技术走向实际应用的重要前提. 研究表明, 基于非手性聚合物与手性掺杂剂的共组装策略能够诱导形成有序的螺旋超分子结构, 从而显著放大CPL响应, 并在不改变聚合物主体结构前提下实现对CPL性质的精准调控. 本文综合评述了非手性聚合物共组装CPL材料的最新研究进展, 并根据手性来源不同, 将体系划分为手性小分子共组装、 手性高分子共组装以及手性对称性破缺共组装3类, 重点围绕其共组装机理与构效关系研究展开了评述. 此外, 进一步概述了该类材料在光电器件中的应用与探索, 并讨论了当前面临的主要挑战与未来的发展方向. 本文旨在为新型高性能CPL材料的设计与开发提供有价值的参考与思路.

Abstract:

Circularly polarized luminescence(CPL) materials have attracted considerable attention in recent years owing to their promising applications in 3D displays, information encryption, and bioimaging. The luminescence dissymmetry factor(glum) is a key parameter to evaluated CPL materials. Effectively enhancing glum is not only one of the core challenges but also a crucial prerequisite for advancing CPL technologies toward practical applications. Recent studies have demonstrated that a co-assembly strategy involving achiral polymers and chiral dopants can induce the formation of ordered helical supramolecular structures, thereby significantly amplifying CPL responses while enabling precise modulation of CPL properties without altering the polymer backbone. This review provides a systematic overview of recent advances in achiral-polymer-based co-assembled CPL materials. According to the chiral source, these systems are categorized into three types: co-assembly with chiral small molecules, co-assembly with chiral macromolecules, and co-assembly induced by chiral symmetry breaking. Particular emphasis is placed on their co-assembly mechanisms and structure-property relationships. In addition, this review outlines recent progress in the application of these materials in optoelectronic devices and discusses the major challenges currently faced in the field, as well as future development directions. This review aims to offer valuable insights and guidance for the rational design and development of next-generation high-performance CPL materials.

Key words: Circularly polarized luminescence, Achiral polymer, Co-assembly, Luminescence dissymmetry factor, Noncovalent interaction
