Anthracene compound and organic light-emitting device comprising same
Provided is an anthracene compound of Chemical Formula 1: wherein, in Chemical Formula 1: D is deuterium; n1 is 8; n2 is 7; and L is a direct bond or a substituted or unsubstituted arylene group, and an organic light emitting device including the same. Including a compound of Chemical Formula 1 in an organic light emitting device can lower the driving voltage and enhance light efficiency. In addition, lifetime properties of the device can be enhanced by thermal stability of the compound. The compound of Chemical Formula 1 has an advantage in terms of production costs since the amount of deuterium source used in the preparation is reduced.
