    摘要： The present invention relates to an electroluminescent device. More specifically, the electroluminescent device according to the present invention is comprised of a first electrode; a second electrode; and at least one organic layer(s) interposed between the first electrode and the second electrode; and the organic layer comprises one or more organic electroluminescent compound(s) represented by Chemical Formula (1) as host material: L1L2M(Q)y   Chemical Formula 1 wherein, the ligands, L1 and L2 are independently selected from the following structures: wherein, M represents a divalent or trivalent metal; y is 0 when M is a divalent metal, while y is 1 when M is a trivalent metal; Q represents (C6-C60)aryloxy or tri(C6-C60)arylsilyl, and the aryloxy or triarylsilyl of Q may be further substituted by (C1-C60)alkyl or (C6-C60)aryl. The electroluminescent devices according to the invention exhibit excellent color purity and luminous efficiency.

    摘要： 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.
