A compound and an organic electroluminescent device. The structural formula of the compound is represented by formula (1) below: Z1-Z3 are the same or different and are each independently CH or N, and Z1-Z3 are not CH at the same time; Ar1 is phenyl or deuterated phenyl; Y is O; and Ar2 is C1-C4 linear or branched alkyl, C1-C4 deuterated linear or branched alkyl, C3-C10 cycloalkyl, C3-C10 deuterated cycloalkyl, C3-C6 cycloalkenyl, C3-C6 deuterated cycloalkenyl, phenyl, naphthyl, anthracenyl, phenanthryl, deuterated phenyl, deuterated naphthyl, deuterated anthracenyl, or deuterated phenanthryl. The compound represented by formula 1 is used as the main material of a light-emitting layer and is applied to an organic electroluminescent device, and the service life of the prepared organic electroluminescent device is greatly increased, thus said compound has broad application prospects. |
