Abstract EN
In this work, new di-acid monomers 4, 4’-di-carboxillic-2”-chloro-4”- nitro triphenylamine (Di-CO2H-1), 4, 4’- di-carboxylic -2”,4”,6”-trichloro-triphenylamine (Di-CO2H-2) were synthesized by reaction of p-cyanobenzofluride with two aromatic amines (2-chloro 4-nitro aniline and 2,4,6-trichloro aniline by aromatic nucleophilc substitution method to produce two di cyano intermediates compounds 4, 4’-Dicyano-2”-chloro-4”- nitro triphenylamine (Di-CN1) and 4, 4’-dicyano-2”,4”,6”-trichloro-triphenylamine (Di-CN2) which form final di-carboxylic monomers after alkaline hydrolysis.
Finally, these monomers react with two different aromatic di amines, phenylene diamins and benzidine respectively via polycondensation reaction to form final polyamides 2”-chloro-4”- nitro -triphenylamine-4, 4'-polyphenylbenzamide (Pa), 2”,4”,6”-trichloro-triphenylamine -4,4'-polyphenylbenzamide (Pb), 2”-chloro-4”- nitro triphenylamine-4,4'- polyphenylbiphenylamide (Pc), 2”,4”, 6”-trichloro-triphenylamine-4,4’- polyphenylbiphenylamide (Pd).
The chemical structure of these polymers characterized by FTIR and NMR techniques.
The polyamides showed a good thermal stability with height glass transition temperatures (Tg).
Thin casting films of these polyamides in cyclic voltammetry (C.V) on glass substrate 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
