The present invention relates to the technical field of organic light emitting diodes (OLED), and provides a compound having a thermally activated delayed fluorescence (TADF) property. The structure of the compound is shown in a formula 1, wherein Ar represents C6-C20 aryl or C5-C20 heteroaryl; D and D represent electron donating groups; A and A represent electron accepting groups; m,n, p and q are separately and independently selected from 1,2,3; D, D, A and A are separately connected to a benzene ring connected with the Ar; D and D are ones separately and independently selected from C1-C20 alkyl, C3-C20 cycloalkyl, C1-C20 alkoxy, C3-C20 heterocyclyl, C6-C40 aryl, C4-C40 heteroaryl, C10-C60 fused heteroaryl, C10-C60 fused heteroaryl, carbazole groups, diphenylamine groups and acridinyl groups; and A and A are separately and independently selected from nitrogen-containing heterocyclic substituents, cyano-containing substituents, carbonyl-containingsubstituents, sulfone substituents, and phosphorus-containing oxygen-containing substituents. The compound provided by the invention is suitable for being used as luminescent host or guest materials of OLED. The invention also provides a display panel and a display device comprising the compound.
