    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.

    摘要翻译： 本发明涉及电致发光器件。 更具体地，根据本发明的电致发光器件包括第一电极; 第二电极; 以及介于所述第一电极和所述第二电极之间的至少一个有机层; 有机层包含一种或多种由化学式（1）表示的有机电致发光化合物作为主体材料：<？in-line-formula description =“In-line formula”end =“lead”？> L1L2M（Q ）y化学式1 <？in-line-formula description =“In-line Formula”end =“tail”？>其中，配体L1和L2独立地选自以下结构：其中，M表示二价或 三价金属 当M为二价金属时，y为0，而当M为三价金属时y为1; Q表示（C 6 -C 60）芳氧基或三（C 6 -C 60）芳基甲硅烷基，Q的芳氧基或三芳基甲硅烷基可以进一步被（C 1 -C 60）烷基或（C 6 -C 60）芳基取代。 根据本发明的电致发光器件表现出优异的色纯度和发光效率。
