Electrochemical synthesis, characterization and electrochromic behavior of poly(4-aminodiphenylamine-co-4,4′-diaminodiphenyl sulfone)

Conductive organic polymers: An electrochemical route for the polymerization of dapsone

“…It was observed that the film exhibits electroactivity only up to pH 7.0. Figure 3b shows As previously stated, Manisankar and co-workers [5][6][7][8] prepared dapsone films in a wide potential window (0.0 to ≥ 1.3 V) which blocked the electrode surface. We carried out an experiment similar to theirs, using a wider potential window (0.00 to 1.50 V), while keeping the other parameters the same (scan rate of 1.00 V s  and pH 1.0).…”

“…In such conditions, they showed that dapsone undergoes an irreversible oxidation process in the potential range of 1.1 to 1.9 V using Ag/AgCl reference electrode, and they attributed the current signal loss after the first anodic scan to the homopolymerization of dapsone [5,6,8], with the resulting formation of a low conductive film.…”

“…Polydapsone belongs to this family, and the first report found on its synthesis is attributed to Dan and Sengupta [2], who prepared the polymer through a chemical oxidative method. Thereafter, conductive copolymers of dapsone with aniline [3], pyrrole [4], diphenylamine [5], and 4-aminodiphenylamine [6] have been prepared through chemical and electrochemical methods, showing electroactivity.…”

Chemical Synthesis and Characterization of Poly(phenylhydrazine-co-4,4′-diaminodiphenyl Sulphone)

“…Electrochemically synthesized copolymer of aniline (ANI) and 4,4′-diaminodiphenyl sulfone (DADPS) 20 exhibited novel electrochromic properties. Copolymers of diphenylamine (DPA) and 4-aminodiphenylamine (ADPA) with 4,4′-diaminodiphenyl sulfone (DADPS) were prepared 21,22 characterized and their electrochromic properties also evaluated.…”

Electrochemical synthesis of polymer based on 4-(2-furyl) benzenamine: Electrochemical properties, characterization and applications

“…Furthermore, their potential use for advanced technological applications including light emitting diodes, photovoltaics, optical switches, anticorrosion protection and sensors has motivated the design and synthesis of new conjugated polymers with unique properties [6][7][8][9][10][11][12][13][14]. PANI and its derivatives are an important family of intrinsically conductive polymers which have been widely used in making of new electrical and optical devices [15][16][17][18][19]. High stability, low cost, easy preparation, and unique electrochemical properties of PANI offer a wide variety of applications [20][21][22][23].…”
