癌症是世界上导致死亡的主要原因之一,其发病率不断上升。光疗以其无创、无耐受、小副作用、操作方便等优势,已成为癌症精准治疗的新范式。自2001年唐本忠院士团队发现聚集诱导发光(AIE)现象以来,具有该性质的荧光材料被广泛用作高效光敏/光热试剂。因其高度扭曲的分子结构,避免了聚集态下的平面堆叠问题,从根本上解决了传统荧光材料聚集淬灭现象,显著提高了量子产率和光稳定性。作者详细对AIE材料作为光敏剂、光热剂及显影剂在癌症光疗(光动力治疗、光热治疗、光声成像)以及联合治疗中的最新应用进行了综述,并展望其未来发展趋势。

Cancer is a leading cause of death globally, with its incidence rate on the rise. Phototherapy has emerged as a novel approach for precise cancer treatment, offering benefits such as non-invasiveness, tolerability, minimal side effects, and ease of operation. Since Prof. Ben Zhong Tang conceptually coined aggregation-induced emission (AIE) in 2001, AIE materials have been extensively applied as efficient photosensitive and photothermal agents. Thanks to their highly twisted molecular structure, AIE materials avoid the issue of π-π stacking in aggregated states, thereby fundamentally addressing the aggregation-caused quenching problem observed in traditional fluorescent materials. This advancement leads to a significant enhancement in quantum yield and photostability. Herein, the author comprehensively reviews the latest applications of AIE materials as photosensitizers, photothermal agents, and diagnostic agents in cancer phototherapy.
