The invention belongs to the technical field of luminescent materials, and discloses a
luminescent material having aggregation-induced emission property as well as preparation and application thereof.A molecular general formula of the
luminescent material is as shown in a formula I which is shown in the description, wherein R1 and R2 are different or same
electron donating or
electron withdrawinggroups, and R3 and R4 are simultaneously
hydrogen or methoxy groups. The
luminescent material disclosed by the invention is stable in structure, has the aggregation-induced emission property and is good in luminescent performance, and the highest efficiency of crystalline-state fluorescent quanta can be up to 20.7 percent; meanwhile, a preparation method of the luminescent material is simple in operation, gentle in
reaction conditions and high in reaction yield; the luminescent material has the advantages that
solid-state
luminescence can be realized, the cost of raw materials is low, regeneration is realized, regulation of light color can be easily realized through accessing different
electron donating and electron withdrawing groups, and the like, and the luminescent material is beneficial for large-scale popularization, and the problem of
energy depletion is solved; meanwhile, the luminescent material has
mechanoluminescence property, and can be applied to the fields of fake prevention, real-
time pressure change monitoring and the like. The formula is shown in the description.
