Compound with aggregation-induced emission property as well as preparation method and application thereof

The invention discloses a compound with aggregation-induced emission property as well as a preparation method and application thereof, electron donor and acceptor groups are introduced into a molecular structure, HOMO-LUMO energy levels of molecules are regulated and controlled, and aggregation-induced emission compounds with different emission colors and high brightness are obtained. The compound has the advantages of large Stokes shift, strong two-photon absorption, good biocompatibility and excellent light stability. Such aggregation-induced emission compounds can specifically image lipid droplets. In addition, the compound can effectively generate active oxygen under an illumination condition, so that the compound can be used for two-photon excited organelle targeted photodynamic therapy. In addition, the compound with the aggregation-induced emission property effectively overcomes the defect of fluorescence quenching caused by aggregation of the traditional fluorescent dye. 本发明公开了具有聚集诱导发光性质的化合物及其制备方法和应用，
