First claim

The invention claimed is:

1. A compound of Chemical Formula 1:

wherein, in Chemical Formula 1:
R1 and R2 are the same as or different from each other, and each independently is a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkylaryl group, or a substituted or unsubstituted aryl group;
R3 to R8 are the same as or different from each other, and each independently is hydrogen, deuterium, a nitrile group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted silyl group, a substituted or unsubstituted amine group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
L1 and L2 are the same as or different from each other, and each independently is a direct bond, a substituted or unsubstituted arylene group, a substituted or unsubstituted monocyclic or dicyclic heteroarylene group, a substituted or unsubstituted divalent dibenzofuran group, a substituted or unsubstituted divalent dibenzothiophene group, a substituted or unsubstituted divalent phenoxazine group, or a substituted or unsubstituted divalent phenothiazine group;
A and B are the same as or different from each other, and each independently is a substituted or unsubstituted aryl group, a substituted or unsubstituted monocyclic or dicyclic heteroaryl group, a substituted or unsubstituted dibenzofuran group, a substituted or unsubstituted benzonaphthofuran group, a substituted or unsubstituted dibenzothiophene group, a substituted or unsubstituted benzonaphthothiophene group, a substituted or unsubstituted phenoxazine group, a substituted or unsubstituted phenothiazine group, a substituted or unsubstituted phenanthroline group, a substituted or unsubstituted benzoquinoline group, a substituted or unsubstituted arylamine group, a substituted or unsubstituted silyl group, or a substituted or unsubstituted phosphine oxide group, or one of the following substituents:

wherein:
Ra to Rh are the same as or different from each other, and each independently is hydrogen, deuterium, a nitrile group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted silyl group, a substituted or unsubstituted amine group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
a and h are each an integer of 0 to 3, b is an integer of 0 to 8, c and f are each an integer of 0 to 4, d is an integer of 0 to 7, e is an integer of 0 to 10, and g is an integer of 0 to 9,
wherein for variables R1-R8, L1, L2, A, B, and Ra to Rh, when a substituent is substituted, it is substituted with any one, two, or more substituents selected from the group consisting of deuterium, a nitrile group, an alkyl group, a cycloalkyl group, an alkoxy group, an aryloxy group, an alkenyl group, a silyl group, a boron group, an amine group, an aryl group, and a heterocyclic group.

2.
