摘　　要：非互易性手性发光材料通过简单的正反面翻转即可快速实现对圆偏振光的手性可逆切换,因而在新型光电器件和高级光学防伪等领域具有广阔的应用前景.迄今为止,在圆偏振发射中观察到的非互易特性非常罕见,对这一特性的研究为可调控手性发光材料的设计、制备和应用提供了新思路和借鉴意义.本文主要以手性发光膜材料为研究对象,从手性有机染料薄膜、手性液晶薄膜、手性聚合物薄膜以及复合手性膜器件等材料体系介绍了非互易性手性的概念、科学机制和研究领域,并对非互易性手性发光材料面临的挑战和未来的重点研究方向进行了讨论.Nonreciprocal circularly polarized luminescent(CPL) films show circularly polarized emission with opposite chirality from their two sides. Simply flipping such films can achieve chirality inversion in circularly polarized absorption and emission. Therefore, this newly emergent type of chiral film demonstrates both great significance in scientific research and promising application potentials. So far, the nonreciprocal characteristics observed in CPL are extremely rare. The investigations are anticipated to provide a solid scientific base for further exploring novel CPLactive switchable and adjustable materials. This article focuses on chiral luminescent film materials, introducing the concept, scientific mechanism, and research areas of nonreciprocal chiral properties in material systems such as chiral organic dye films, chiral crystal films, chiral helical polymer films, and composite chiral film devices. Additionally, the challenges faced by nonreciprocal CPL-active materials and future research directions are discussed.
