摘　　要：激发态分子内质子转移(ESIPT)的过程包括独特的四能级能态循环和伴随的多重发射,在ESIPT激发态的调控下,通过表现各种光物理过程(非辐射跃迁、辐射跃迁、能量转移、电荷转移等)的平衡和转换关系,ESIPT金属-有机超分子光学材料显示丰富的发光机制和多领域应用。鉴于对ESIPT金属-有机超分子材料性质的认识处于起步阶段,迫切需要建立新的调控发光机制策略,综述了ESIPT金属-有机超分子材料的构建及发光调控,对未来新型光功能材料的构建具有指导意义,同时加强认识原子光谱项在超分子材料领域的理论价值。The process of excited-state intramolecular proton transfer(ESIPT)involves a unique four-level energy state cycle and associated multiple emissions.Under the regulation of ESIPT excited states,metal-organic supramolecular optical materials exhibit a rich variety of luminescence mechanisms and applications across multiple fields by demonstrating the balance and transformation relationships of various photophysical processes(non-radiative transitions,radiative transitions,energy transfer,charge transfer,etc.).Given that the understanding of the properties of ESIPT metal-organic supramolecular materials is still in its infancy,there is an urgent need to establish new strategies for regulating luminescence mechanisms.This paper reviews the construction and luminescence regulation of ESIPT metal-organic supramolecular materials,which is of guiding significance for the construction of novel photo-functional materials in the future and simultaneously strengthens the theoretical value of atomic spectral terms in the field of supramolecular materials.
