Copolymers (P( PDA /Ar)) of o ‐phenylenediamine with aniline (Ar = ANi ), 3,4‐ethylenedioxythiophene (Ar = EDOT ) and 2,3,5,6‐tetrafluoroaniline (Ar = TFANi ) were synthesized via polycondensation initiated by ammonium persulfate. The NH 2 group content in the copolymers was determined by analyzing the 1 H NMR spectra of the N ‐acetylated copolymers. Copolymers crosslinked by viologen (1,1'‐disubstituted 4,4'‐bipyridinium dichloride) were obtained by reaction involving the reactive NH 2 groups in the copolymers. The absorption wavelengths of solutions of the copolymers and the electrochemical oxidation and reduction potentials of cast films of the copolymers were affected by the electrical properties of the Ar unit. © 2016 Society of Chemical Industry
