By using the aromatic nucleophilic displacement reaction of 4-fluorobenzonitrile with three aniline-derivatives using sodium hydride as the base synthesized new dinitriles intermediates (A-CN), (B-CN) and (C-CN). After alkaline hydrolysis of these resultants three di acid monomers e.g., 4,4-dicarboxy-4-ethylenetriphenylamine (A-OH), 4,4-dicarboxy-4-isopentyl-triphenylamine (B-OH), 4-dicarboxy-4-phenoxy-triphenylamine (C-OH) were obtained. A series of poly(amine-amide)s were prepared by the phosphorylation poly-condensation reaction with different aromatic diamines. The chemical structures of all the resultant compounds and poly(amine-amide)s were identified by FTIR, 1H and 13C NMR techniques. These aromatic poly(amine-amide)s exhibited excellent thermal stability with high glass transition temperatures (Tg). Solutions diluted in N-methyl pyrrolidone of these polyamides appeared a strong UV-visible absorption in the blue region. These polymers exhibited cyclic voltammetry of the resulting polyamides films cast onto an ITO-coated glass substrate in dry acetonitrile containing 0.1 M of tetrabutylammonium perchlorate as an electrolyte exhibited one oxidation redox couples.
