    Abstract: Provided is a compound of Chemical Formula 1: where R1 and R2 are each independently hydrogen, a substituted or unsubstituted C1-60 alkyl, a substituted or unsubstituted C1-60 alkoxy, a substituted or unsubstituted C1-60 haloalkyl, a substituted or unsubstituted C1-60 haloalkoxy, halogen, cyano, tri(C1-60 alkyl)silyl, a substituted or unsubstituted C6-60 aryl, or a substituted or unsubstituted C2-60 heteroaryl containing at least one of O, N, Si and S,
    R3 and R4 are each independently hydrogen, deuterium, a substituted or unsubstituted C1-60 alkyl, a substituted or unsubstituted C1-60 alkoxy, a substituted or unsubstituted C1-60 haloalkyl, a substituted or unsubstituted C1-60 haloalkoxy, halogen, cyano, tri(C1-60 alkyl)silyl, or a substituted or unsubstituted C2-60 heteroaryl containing at least one of O, N, Si and S, and
    Ar is C6-60 aryl, or C2-60 heteroaryl containing at least one of O, N, Si and S, wherein the C6-60 aryl, or C2-60 heteroaryl is substituted with 1 to 5 substituents each selected from the group consisting of a substituted or unsubstituted C1-60 alkyl, a substituted or unsubstituted C1-60 alkoxy, a substituted or unsubstituted C1-60 haloalkyl, a substituted or unsubstituted C1-60 haloalkoxy, halogen, cyano, and tri(C1-60 alkyl)silyl,
    and an organic light emitting device including the same.

    Abstract: Provided are anthracene derivatives of Chemical Formula 1: wherein: X1 is O or S; R1 and R2 are the same as or different from each other, and each independently is hydrogen, deuterium, a nitrile group, a halogen groups a substituted or unsubstituted alkyl group, a substituted or unsubstituted silyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group, or bond to adjacent groups to form a substituted or unsubstituted ring; Ar is a substituted or unsubstituted heteroaryl group comprising O or S; and a is an integer of 0 to 9, and b is an integer of 0 to 8, and when a is 2 or greater, R1s are the same as or different from each other, and when b is 2 or greater, R2s are the same as or different from each other. Also provided are organic light emitting devices comprising same.
