Novel compound and organic light emitting device comprising the same

Abstract

A compound of Chemical Formula 1: where X1 and X2 are each independently O or S; A1 is a benzene ring fused with adjacent pentagonal and benzene rings; A2 is a naphthalene ring fused with an adjacent pentagonal ring; Ar is a substituted or unsubstituted C6-60 aryl, a substituted or unsubstituted C2-60 heteroaryl containing a heteroatom of O or S, or a substituted or unsubstituted C2-60 heteroaryl containing a heteroatom of N and at least one selected of O and S; R1 and R2 are each independently hydrogen, deuterium, halogen, cyano, or a substituted or unsubstituted C1-60 alkyl; and the other substituents are as defined in the specification; and an organic light emitting device including the same. The organic light emitting device including the compound of Chemical Formula 1 in an organic material layer exhibits improved efficiency, low driving voltage and/or improved lifetime characteristics.
