Compound, display panel, and display apparatus
Abstract:
The present disclosure relates provides an compound represented by Chemical Formula 1, in which Ar1, Ar2, Ar3 and Ar4 are C6-C40 aryl, or C5-C40 heteroaryl; R1 and R2 are —C(R)2—, —N(R)—, —O—, or —S—; X1, X2 and X3 are C or N; L1 and L2 are phenylene, naphthylene, or biphenylene; Y1 and Y2 are each an electron-withdrawing group selected from a N-containing heterocyclic group, or a cyano-containing group. The compound of the present disclosure has bipolar characteristics of simultaneously transmitting holes and electrons. The bipolar transmission host is beneficial to charge transmission balance in the light-emitting layer, and can widen the exciton recombination region, to simplify the device structure and improving device efficiency. The present disclosure further provides a display panel and a display apparatus.
