Abstract A new triphenylamine-based aromatic dicarboxylic acid monomer, 4-tert-butyl-4′, 4 ″-dicarboxytriphenylamine (2), was synthesized from the cesium fluoride mediated N, N- diarylation reaction of 4-tert-butylaniline with 4-fluorobenzonitrile and subsequent alkaline hydrolysis of the dinitrile intermediate. A series of six aromatic polyamides 4a-4f with tert- butyltriphenylamine groups was prepared from the newly synthesized dicarboxylic acid ...
