摘要： A D-A type organic light-emitting material includes a donor moiety and an acceptor moiety. The donor moiety is represented as follows: L is selected from any of aryl, heteroaryl, fused aryl and fused heteroaryl. When L is selected from any of aryl and heteroaryl, aryl and heteroaryl each have one or more substituents each selected from any of deuterium, tert-butyl, phenyl, cyano and methylimino, and at least one substituent is selected from cyano and methylimino. When L is selected from any of fused aryl and fused heteroaryl, fused aryl and fused to heteroaryl each have or do not have a substituent. When fused aryl and fused heteroaryl each have a substituent, the substituent is selected from any of deuterium, tert-butyl, phenyl, cyano and methylimino. The acceptor moiety is selected from any of a substituted or unsubstituted fused aromatic rings and a substituted or unsubstituted fused heterocyclic ring.

摘要： An organic electroluminescent device, a display panel, and a display device are disclosed. The organic electroluminescent device includes: an anode and a cathode disposed opposite to each other, a light emitting layer located between the anode and the cathode, an electron blocking layer located between the light emitting layer and the anode, and a hole transport layer located between the electron blocking layer and the anode. The light emitting layer includes an exciplex formed by mixing an electron-type host material and a hole-type host material, and a guest material with which the exciplex is doped. The electron mobility of the hole transport layer is greater than that of the electron blocking layer.

摘要： A light-emitting device includes a hole blocking layer including one or more of compounds shown in following formula (1)a and formula (1)b. Z1 to Z11 are selected from H or R. R, R1 and R2 are each selected independently from deuterium, halogen, cyano, nitryl, amino, C1-C40 alkyl, C2-C40 alkenyl, C2-C40 alkynyl, C3-C40 cycloalkyl, C3-C40 heterocycloalkyl, C6-C60 aryl, C5-C60 heteroaryl, C1-C40 alkoxy, C6-C60 aryloxy, C3-C40 alkylsilyl, C6-C60 arylsilyl, C1-C40 alkylboron, C6-C60 arylboron, C6-C60 arylphosphinylene, C6-C60 monoaryl or diaryl phosphino and C6-C60 arylamino. R3 is selected from heterocyclyl and fused heterocyclyl.
