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.
Since the organic electroluminescent compounds according to the invention have good luminous efficiency and excellent color purity and life property of material, OLED's having very good operation life can be manufactured therefrom.
本发明涉及新型有机电致发光化合物,以及将其用作电致发光材料的有机电致发光器件。具体地说,根据本发明的有机电致发光化合物的特征在于它们由化学式(1)表示:
其中,A 和 B 独立地代表 CR7 或 N,但 A 和 B 不能同时是 CR7 或 N;X 是 O 或 S。
由于本发明的有机电致发光化合物具有良好的发光效率和优异的颜色纯度以及材料的寿命特性,因此可以用其制造出具有极佳工作寿命的有机发光二极管。
