A new diphenylamine di-acid monomer (4,4'-dicarboxy-6-methylnaphthalene-diphenylamine) (D-COOH) have been synthesized via, aromatic nucleophilic substitution reaction of p-cyanobenzofluride with 5-methoxynaphthalene-1-amine to produce di-cyanide compound
(4,4'-dicayno-6-methylnaphthalene-diphenylamine) (D–CN), as intermediate then after alkaline hydrolysis of this intermediate to form final di-carboxylic monomer (D-COOH). A series of polyamides (P-CONH) were synthesized using poly-condensation reaction method with three aromatic diamine compounds (benzidine, 4,4'-methylenedianiline,and 4,4'-oxydianiline). The chemical structures of all result intermediates and polyamides were characterized using FTIR and 1HNMR techniques. All the product polyamides have high solubility in many polar organic solvents, forming thin strong tough films. Polyamides also gave finest thermal stability with height glass transition temperatures (Tg). Solutions of these polyamides in NMP solvent exhibited strong photoluminescence PL. Thin films casting of these polyamides in cyclic voltammetry (C.V) which made from plated glass base of iridium-tin oxide (ITO) as working electrode in dry CH3CN solvent contains 0.1 M of tetrabutylantimoneperchlorate (TBAP) as an electrolyte gave one redox wave.
