Electropolymerized aniline derivative films possessing selective electron-transfer mediation properties for the redox reaction of dissolved substrates.

Reaction of Dissolved p-Dimethoxybenzene on a Polyaniline-Modified Electrode

“…6 Analogously, the PANI film is permselective toward p-dimethoxybenzene and p-methoxyphenol. In order to examine the kinetics of the selective permeation, RDE voltammetry was employed.…”

Formation of electroactive film on electrode surfaces by electro-oxidation of naphtho[1,8-cd][1,2]dithiole

“…3, whose chemical structures are (A), (B), (C) and (D), respectively, linked with one naphthalene ring at 4-or 5-position and dithio-function group of another DTN, each 3-and 6-position of two naphthalene rings, 4-and 5-positions of two DTN naphthalene rings, or head to head of dithio-function group of two DTNs, are assumed for the initial stages of the electropolymerization. From the previous paper [13], in the electropolymerization of many aromatic compounds, a scheme for a polymerization reaction mechanism via such a radical-radical coupling at the 3-and 6-positions of naphthalene may be conceivable as shown in Fig. 1A.…”

“…The peaks observed in the range 750-1250 cm À1 for both DTN monomer and poly(DTN) film are ascribable to the in-plane and outof-plane bending modes in the naphthalene rings. The common absorption peaks in the region 1300-1600 cm À1 , which are common to the DTN monomer and poly(DTN), are characteristics of the stretching vibration mode of the C@C bonds of the aromatic nuclei [6,7,11,13]. Further the common absorption peaks 568 and 532 cm À1 for the DTN monomer and the poly(DTN) film, respectively, which are characteristics of the asymmetrical combination mode of S-S stretches of 1,8-disubstituted naphthalene, were observed [41].…”

“…In continuation of our research concerning the preparation of electroactive films by electropolymerization, our interest has extended to the aromatic compounds having a -SH functional group. We have introduced that aromatic compounds with more than two -NH 2 , -OH and/or -SH groups can be considered as a new monomer candidate for electropolymerization [4][5][6][7][8][9][10][11][12][13]. In the case of o-aminothiophenol [4], the resulting polymer possessed a unique structure of double-stranded ladder structure, where the linkage of an aliphatic thioether gives a compound produced with a C-S-C bond, and revealed the reversible redox activity.…”

Poly(1,2‐diaminobenzene) and poly(1,3‐diaminobenzene): Synthesis, characterization, and properties

“…These functions include electrochemical diode properties, 19 electron transfer mediation catalysis, 19 and protection metal corrosion (anthiphoto corrosion). 20,21 The incorporation of metal cations into polymers is important for the potential applications, but it is very difficult due to the repulsion interactions between the metal and the radical cations of the polymer.…”
