The invention belongs to the field of organic optoelectronic materials, and in particular relates to a maleic hydrazide derivative, a preparation method and application thereof, and its structural formula is as follows: In general formula (1), Y is hydrogen, C 1-10 straight-chain alkyl, C 1-10 branched alkyl; Ar 1 , Ar 2 independently represent hydrogen, C 5-20 aryl- Ar-R or -R, and Ar 1 and Ar 2 are not hydrogen at the same time; Ar is phenyl, biphenyl, terphenyl, naphthyl, anthracenyl or phenanthrenyl, and the compound is based on maleic hydrazide The core is not easy to crystallize between molecules, not easy to aggregate, and has the characteristics of good film formation. When the compound of the present invention is used as a material for a light-emitting layer of an OLED light-emitting device, the produced OLED device has good optoelectronic properties. |
