LUMINESCENT COMPOUNDS AND ELECTROLUMINESCENT DEVICE USING THE SAME

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.

Synthesis and properties of 9,9-diarylfluorene-based triaryldiamines

(matrix presented) 9,9-Diaryl-2,7-dibromofluorene was synthesized by a triflic acid promoted Friedel-Crafts reaction. Introduction of diarylamino groups at its C2 and C7 positions by a Pd-catalyzed amination results in the formation of a novel class of triaryldiamines. The 9,9-diaryl substituents at the central linkage play a less important role in the photophyscial properties but affect the oxidation potential and improve the morphological stability of these new triarylamines.
