Research on strategies to enable organic long-persistent luminescence (LPL) emission with circularly polarized luminescence (CPL) characteristics is still very rare due to the lack of an unambiguous light-emitting mechanism. Herein, circularly polarized long-persistent luminescence (CPLPL) of a pair of axial chiral molecules as the guest is induced under ambient conditions by exploiting the long-lived charge separation of the host–guest doping system, whose LPL performance can be further promoted by introducing a rigid polymer network to enhance the charge separation efficiency between host and guest. Based on these CPLPL materials, an effective combination of CPL and LPL properties that is “difficult to copy” is revealed for information encryption and anticounterfeiting applications. This work is expected to stimulate a research boom of CPLPL materials, and will hopefully promote the development of organic LPL systems.

长寿命电荷分离诱导的具有圆偏振特性的有机长余辉发光

由于缺乏明确的发光机制，关于实现具有圆偏振发光（CPL）特性的有机长余辉发光（LPL）发射的策略的研究仍然非常少。在此，通过利用主客体掺杂系统的长寿命电荷分离，在环境条件下诱导作为客体的一对轴向手性分子的圆偏振长余辉发光（CPLPL），其LPL性能可以通过以下方式进一步提升引入刚性聚合物网络以提高主客体之间的电荷分离效率。基于这些CPLPL材料，揭示了“难以复制”的CPL和LPL属性的有效组合，用于信息加密和防伪应用。
