Abstract
[GRAPHICS] 9,9-Diaryl-2,7-dibromofluorene was synthesized by a triflic acid promoted F riedel-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 linkag e play a less important role in the photophyscial properties but affect the oxidation potential and improve the morphological stability of these new t riarylamines.
