摘　　要：Materials exhibiting persistently ultralong room-temperature phosphorescence(RTP)are capturing significant attention due to their long lifetimes,pronounced Stokes shifts,and efficient exciton utilization[1–3].These attributes position RTP materials as ideal candidates for advanced applications in information security,data storage,light-emitting diodes,bioimaging[4–6].超分子玻璃(SMGs)因其独特的非共价交联无定形结构和卓越的光学性能而受到广泛关注.这些材料内部的多种非共价相互作用促进了超分子玻璃的形成,并构建了一个刚性的分子环境,抑制了三线态激子的非辐射跃迁,从而显著增强了玻璃的室温磷光(RTP)发射性能.此外,具备超长RTP特性的超分子玻璃还具有制备简便、透明度高、硬度强等优点.本文深入探讨了SMGs的制备,超长磷光性质及其光学应用,并指出了未来研究的方向和面临的挑战.我们期望本论文能够为高性能超分子玻璃的设计与制备提供科学的指导,并推动其在更广泛的光子学领域的发展.
