The main aim of this research was to study the
electrochemical behavior of novel optically active poly
(amide-imide)s (PAIs). Polycondensation reactions of a 3,5-
diamino-N-(4-hydroxyphenyl)benzamide with different
synthetic diacid chlorides derivatives based on natural
amino acids resulted in preparation of five different
aromatic–aliphatic PAIs. These polymers were characterized by Fourier transform infrared, proton nuclear magnetic
resonance, and elemental analyses. Also, we used electrochemical impedance spectroscopy for the evaluation of
these novel optically active PAIs for the first time. Presence
of p-substituted phenol groups in the structure of these
polymers has been used for electrochemical investigation.
Results showed that the oxidation currents in five diverse
polymers were affected by their structures. In addition, the
influence of carbon nanotubes on the oxidation of phenolic
groups was studied using carbon paste matrix in an aqueous
buffer solution (pH 7.0).
