1. A heterocyclic compound of Formula I:

OG Complex Work Unit Chemistry
wherein Y is selected from O or S; at least three of X1, X2, X3, X4, X5, X6, X7 and X8 are a N atom and the at least three N atoms are positioned at different rings, and rest are CR2; L1, L2, and L3 are independently selected from single bond, substituted or unsubstituted aromatic groups; Ar1 and Ar2 are independently selected from substituted or unsubstituted aromatic groups or heteroaryl groups; R1 is selected from a hydrogen atom, a deuterium atom, or an aromatic group or a heteroaryl group to be condensed with a ring including X1, X2, X3, and X4, and one of X5 through X8 is bonded to the L1-N(L2Ar1)(L3Ar2) group, and one of X1 through X4 is bonded to R1; and R2 is selected from a hydrogen atom, a deuterium atom, a substituted or unsubstituted C1-C5 alkyl group, a halogen, a cyano group, or an amino group.
