posted on 2001-06-30, 00:00 authored by Ken-Tsung Wong, Zi-Jien Wang, Yuh-Yih Chien, Chien-Lung Wang9,9-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.
