The present invention relates to organic electroluminescent compounds and organic electroluminescent devices employing the same. More specifically, the invention relates to organic electroluminescent compounds containing an anthracenyl group or an aryl group having an anthracenyl substituent m the aryl ring of fluorene or indenofluorene, as a blue electroluminescent material in an organic electroluminescent layer. The electroluminescent compounds according to the invention exhibit high luminous efficiency and excellent life property, so that an OLED device having very good operation lifetime can be prepared therefrom.
本发明涉及有机电致发光化合物和采用这些化合物的有机电致发光器件。更具体地,该发明涉及含有蒽基或在芴或间芴芴环的芳基上具有蒽基取代基的有机电致发光化合物,作为有机电致发光层中的蓝色电致发光材料。根据本发明的电致发光化合物表现出高发光效率和优异的寿命特性,因此可以制备出具有非常良好操作寿命的OLED器件。
