摘要/Abstract

手性分子碳酰亚胺（CMCIs）凭借其独特的π-共轭骨架、优异的光化学稳定性以及可调控的光电性质,为高效圆偏振发光（CPL）材料的设计与开发提供了新的契机。近年来,随着分子设计与精准合成策略的不断发展,研究人员通过提高分子对称性、引入杂环结构以及构建多手性中心等方法,在提升发光不对称因子（g_lum）、荧光量子产率（Φ_PL）和圆偏振发光亮度（B_CPL）等方面取得突破,并揭示了手性产生、传递与放大的内在规律,推动了圆偏振发光体系的发展。然而,如何实现g_lum、Φ_PL与B_CPL的协同优化,是手性功能材料领域的核心挑战。本文系统综述了近年来具有圆偏振发光性质的手性分子碳酰亚胺研究进展,从单链、双链到多链手性共轭螺旋等不同拓扑结构对代表性体系进行了分类总结,重点阐述了分子结构特征、电子跃迁行为与圆偏振发光性能之间的构效关系,分析了影响圆偏振发光性能的关键分子设计因素。最后,对该领域面临的分子设计策略和应用前景做了展望。

Circularly polarized luminescence (CPL), arising from the unequal emission of left- and right-handed circularly polarized light by chiral luminophores, has attracted increasing attention owing to its promising applications in three-dimensional displays, quantum communication, information storage and encryption, bioimaging, and advanced optoelectronic devices. Among various CPL-active materials, chiral molecular carbon imides (CMCIs), derived from rylene diimides (RDI)-based molecular carbon frameworks, have emerged as a unique class of chiral π-conjugated systems. Benefiting from their rigid aromatic skeletons, excellent photochemical stability, large molar extinction coefficients, and tunable molecular structures, CMCIs provide an attractive platform for investigating chirality generation, transmission, amplification, and regulation, while offering opportunities for the development of high-performance CPL materials. In recent years, substantial progress has been achieved in the design and synthesis of CPL-active CMCIs. Through the integration of conjugated fusion and helical distortion strategies, a variety of chiral conjugated helices have been developed, including single-strand chiral conjugated helices (ss-CCHs), double-strand chiral conjugated helices (ds-CCHs), and multiple-strand chiral conjugated helices (ms-CCHs). These systems exhibit diverse topological architectures and distinctive chiroptical properties. Continuous advances in molecular engineering such as enhancing molecular symmetry, introducing heteroatom-annulated structures and constructing multiple chiral centers, have enabled significant improvements in luminescence dissymmetry factors (g_lum), photoluminescence quantum yields (Φ_PL), and CPL brightness (B_CPL). This review systematically summarizes recent advances in CPL-active CMCIs and classifies representative systems according to their molecular topologies. The relationships between molecular structures, electronic transitions, and CPL performance are discussed in detail, with attention paid to the molecular origins of chirality generation, transmission, and amplification. Key factors governing luminescence dissymmetry factors and CPL brightness are analyzed from both structural and photophysical perspectives. Finally, the remaining challenges and future opportunities are highlighted, including the synergistic optimization of g_lum, Φ_PL, and B_CPL, the development of high-performance near-infrared CPL emitters, and the practical implementation of CMCIs in chiral photonic and optoelectronic technologies.

Key words: chirality, molecular carbon imides, circularly polarized luminescence, luminescence dissymmetry factor, photoluminescence quantum yield
