The invention provides an anthracene-containing 8-hydroxyquinoline zinc complex mononuclear crystal with twisted structure, its preparation method and application. The preparation method is as follows: dissolve (E)-2-[2-(9-anthracenyl)vinyl]-8-hydroxyquinoline in N,N-dimethylformamide, add methanol dropwise, and then drop Add pyridine, and finally add N,N-dimethylformamide solution containing zinc salt, place the resulting mixed solution in a sealed container, react at 65-85°C until crystals precipitate, filter, wash the crystals with methanol, and dry them. The anthracene-containing 8-hydroxyquinoline zinc complex has high luminous intensity, good thermal stability and long fluorescence lifetime, and has potential economic value in the preparation of luminescent materials or photoelectric light-emitting devices and other applications. The anthracene-containing 8-hydroxyquinoline ligands and complexes all have aggregation-induced luminescent phenomenon, and can be widely used in the fields of chemical sensing, biosensing, biomarking, electroluminescence, logic gate devices and the like. |
