Abstract

An organic compound, an electroluminescent material and its application are provided in the present disclosure. The organic compound includes a structure:X is selected from O, S, N—RN1, and CRC1RC2; Y is selected from O, S, N—RN2, CRC3RC4, O═S═O, SiRS1RS2, O═P—Ar1, and S═P—Ar2, RN1, RN2, RC1, RC2, RC3, RC4, RS1, and RS2 are each independently selected from C1˜C20 linear or branched alkyl, C6˜C40 aryl, and C3˜C40 heteroaryl; Ar1 and Ar2 are each independently selected from C6˜C40 aryl and C3˜C40 heteroaryl; L1, L2, L3, L4, and L5 are each independently selected from a single bond, C6˜C40 arylene, and C3˜C40 heteroarylene; R1, R2, R3, R4, and R5 are each independently selected from deuterium, C1˜C20 linear or branched alkyl, C1˜C20 alkoxy, C1˜C20 alkylthio, C3˜C20 cycloalkyl, C6˜C40 aryl, C3˜C40 heteroaryl, and C6˜C40 arylamino; and n1, n2, n3, n4, n5, m1, m2, m3, m4, and m5 are integers each independently selected from 0-2.
