摘　　要：有机-无机复合荧光纳米材料制备简便,生物相容性好,成像性能优异,在化学和生物传感、生物成像、催化及能源材料等领域受到很多关注.传统的荧光有机小分子与无机材料复合时,常发生荧光猝灭,而聚集诱导发光(Aggregation-Induced Emission,AIE)有机小分子在聚集态具有高发光量子产率,为有机-无机复合荧光纳米材料的研究提供了机遇.由于AIE有机小分子功能化的无机纳米材料独特的优点,人们对其设计、合成及应用进行了较多研究.综述了AIE有机小分子和多种类型的无机纳米结构(金属纳米颗粒、钙钛矿材料、层状材料、氧化物、硫化物等)复合材料的制备和应用的新进展,特别是在化学和生物传感、生物成像、药物输运、光热治疗、催化以及能源等领域的应用,并对其发展前景进行了展望.Fluorescent organic-inorganic nanocomposites have attracted more and more attention in the fields of chemical and biological sensing,biological imaging,energy materials,etc.,due to their simple preparation,good biocompatibility and excellent imaging performance.Fluorescence quenching often occurs when traditional fluorescent organic small molecules are combined with inorganic materials,however,organic molecules with aggregation-induced emission(AIE)properties,which show high luminescence quantum yields in the aggregated state,provide opportunities for fluorescent organic-inorganic nanocomposites.Because of the unique advantages of the AIE fluorophore-functionalized inorganic nanomaterials,a great deal of research has been carried out on the design,synthesis and applications of such composite materials.The recent progress in the organic-inorganic composites of AIE-active organic small molecules and various types of inorganic nanomaterials(metal nanoparticles,perovskites,layered materials,oxides and sulfides,etc.)is summarized.In particular,the typical applications of these nanocomposites in chemical sensing,biosensing,bioimaging,drug transport,catalysis,photothermal therapy and energy materials are summarized.The prospects of these AIE-active organic-inorganic nanocomposites are also discussed.
