Phenanthroline compound and organic light emitting element comprising the same

The present invention relates to a phenanthroline compound and an organic light emitting device including the same. The phenanthroline compound is represented by chemical formula 1. In the chemical formula 1, Ar_1, Ar_2, Ar_3, Ar_4, Ar_5, and Ar_6 are each independently selected from the group consisting of hydrogen, a single bond, a substituted or unsubstituted aryl group having 3 to 30 carbon atoms, and a substituted or unsubstituted heteroaryl group having 3 to 30 carbon atoms. Accordingly, the organic light emitting device including the phenanthroline compound has improved excellent efficiency. 본 발명은 페난트롤린 화합물 및 이를 하나 이상의 유기층에 포함함으로써 우수한 효율 특성을 나타내는 유기전기발광소자에 관한 것이다.
