Compound and organic light emitting device comprising the same

Abstract

Provided is a compound of Chemical Formula 1: wherein one of X1 to X8 is N, and one of the rest is C bonded to L1, and the rest are each independently CR; R is hydrogen or deuterium; Y is O or S; L1 is a single bond or L2 and L3 are each independently a single bond, phenylene, or naphthylene; Ar1 and Ar2 are each independently phenyl, biphenyl, terphenyl, quaterphenyl, naphthyl, binaphthyl, (naphthyl)phenyl, (phenyl)naphthyl, phenanthrenyl, triphenylenyl, chrysenyl, tetracenyl, benz[a]anthracenyl, benzo[c]phenanthrenyl, fluorenyl, 9,9-dimethylfluorenyl, 9,9-diphenylfluorenyl, spirobifluorenyl, fluoranthenyl, dibenzothiophenyl, dibenzofuranyl, carbazolyl or 9-phenylcarbazolyl, with the proviso that Ar1 and Ar2 are not phenyl at the same time, and Ar1 and Ar2 are each independently unsubstituted or substituted with at least one of deuterium, a C1-20 alkyl, a C3-20 cycloalkyl, or a C6-20 aryl, and an organic light emitting device including the same.
