Page/Page column 15, (2011/04/14)
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.
