COMPOUND AND ORGANIC LIGHT EMITTING DEVICE COMPRISING THE SAME

Abstract

A compound of Chemical Formula 1: wherein: Ar1 is an aryl group having 6 to 60 carbon atoms that is substituted with one or more cyano groups, and is optionally further substituted with deuterium; Ar21 to Ar23 are the same as or different from each other, and are each independently hydrogen, deuterium, or a substituted or unsubstituted aryl group having 6 to 60 carbon atoms; and the other substituents are as defined in the specification; and an organic light emitting device including the same. The compound can be used as a material for an organic material layer of an organic light emitting device, and can be used as a material for a light emitting layer. An organic light emitting device including the compound of Chemical Formula 1 exhibits a low driving voltage, a high efficiency and/or a long service life compared to existing organic light emitting devices.
