Abstract:
The present invention relates to novel organic electroluminescent compounds, and organic electroluminescent devices employing the same as electroluminescent material. Specifically, the organic electroluminescent compounds according to the invention are characterized in that they are represented by Chemical Formula (1): wherein, A and B independently represent CR7 or N, provided that both A and B cannot be CR7 or N at the same time; and X is O or S.
