Novel compound and organic light emitting device comprising the same

Abstract

Provided is a novel compound Chemical Formula 1: wherein: L is a single bond, a substituted or unsubstituted C6-60 arylene, or a substituted or unsubstituted C2-60 heteroarylene containing one or more of N, O and S; L1 and L2 are each independently a single bond or a substituted or unsubstituted C6-60 arylene, Ar1 and Ar2 are each independently a substituted or unsubstituted C6-60 aryl or C2-60 heteroaryl containing one or more of N, O and S, L′ is a single bond or a substituted or unsubstituted C6-60 arylene, Q is a substituted or unsubstituted C6-60 aryl, R is deuterium or deuterium-substituted phenyl, and n is 1 to 8, and an organic light emitting device including the same. Organic light emitting devices that include the compound of Chemical Formula 1 as a host material for the light emitting layer exhibit remarkably improved lifetime characteristics without reducing luminous efficiency.
