An organic electroluminescent material, having a structure as shown in chemical formula 1:

• wherein R2, R4, and R5 are identical or different, and are each independently selected from substituted or unsubstituted aryl with 6-30 carbon atoms, or substituted or unsubstituted heteroaryl with 1-30 carbon atoms;
• R1 and R3 are identical or different, R1 is selected from substituted or unsubstituted phenylene, substituted or unsubstituted biphenylene, substituted or unsubstituted terphenylene, or substituted or unsubstituted naphthylene, and R3 is selected from substituted or unsubstituted arylene with 6-25 carbon atoms, or substituted or unsubstituted heteroarylene with 5-18 carbon atoms;
• substituents of R1, R2, R3, R4, and R5 are identical or different, and are each independently selected from deuterium, cyano, nitro, alkyl group with 1-40 carbon atoms, alkenyl group with 2-40 carbon atoms, alkynyl group with 2-40 carbon atoms, heterocycloalkyl group with 2-40 carbon atoms, aralkyl group with 7-40 carbon atoms, heteroaralkyl group with 2-40 carbon atoms, aryl group with 6-40 carbon atoms, heteroaryl group with 1-40 carbon atoms, alkoxyl group with 1-40 carbon atoms, alkylthio group with 1-40 carbon atoms, alkylsilyl group with 1-45 carbon atoms, arylsilyl group with 6-50 carbon atoms, aryloxyl group with 6-30 carbon atoms or arylthio group with 6-30 carbon atoms;
