圆偏振有机余辉材料具有独特的手性光学特性与持续发光能力，在三维显示、信息存储与加密、手性光电器件等领域展现出良好的应用潜力。文章通过引入轴向手性离子液体与丙烯酰胺(AM)共聚，制备并优化了系列具有圆偏振余辉特性的手性离子液体共聚物。实验结果表明，RPAMVIm BNDHP-1%和S-PAMVIm BNDHP-1%薄膜表现出优异的圆偏振发光性能和持续约6 s的绿色超长余辉，其磷光寿命分别为1.02 s和1.20 s，发光不对称因子分别达到2.09×10-3和-2.52×10-3。基于其良好的余辉特性，该材料被成功应用于对映体识别研究。在302 nm紫外灯照射下，可实现D/L-组氨酸和D/L-苯乳酸的可视化鉴别。本研究不仅成功开发了一种简便高效的手性识别材料，还为设计具有多级信息处理功能和手性传感性能的新型光学材料提供了新思路。
Abstract：Circularly polarized organic afterglow materials with unique chiroptical properties and sustained luminescence capabilities, exhibit significant potential for applications in 3D displays, information storage and encryption, and chiroptical devices. In this study, a series of chiral ionic liquid copolymers with circularly polarized afterglow properties were prepared and optimized by introducing axially chiral ionic liquid copolymerization with acrylamide. The experimental results show that the R-PAMVIm BNDHP-1% and SPAMVIm BNDHP-1% films exhibit excellent circularly polarized luminescence performance, sustained green ultra-long afterglow(～6 s), phosphorescence lifetimes of 1.02 s and 1.20 s, and luminescence dissymmetry factors reaching 2.09×10-3 and-2.52×10-3, respectively. Based on their superior afterglow characteristics, these materials were successfully applied to enantiomer recognition studies. Under the irradiation of 302 nm UV lamp, the visual identification of D/L-histidine and D/L-phenyllactic acid could be achieved. This research successfully developed a simple and efficient chiral recognition material, and also provided design insights for creating new types of optical materials with multi-level information processing capabilities and chiral sensing properties.
