Polymer-coated electrodes: cyclic voltammetry and chronoamperometry of non-ideal systems ? the anodic oxidation of poly(4-vinyl-triphenylamine) films

Synthesis and Characterization of New Triarylamine-Based Polymers

“…The irreversible oxidation process exhibited in this system is considered to be due to oxidative coupling in the TDPA unit. [26,27] No any reduction processes can be observed for both polymers down to -1.5 V vs Ag/AgCl. The results from optical, DSC and electrochemical measurements are summarized in Table 4.…”

Synthesis and electrochemical, optical, and thermal properties of polycarbosilanes with silylene–vinylene–phenylene–vinylene backbones and triphenylamine or carbazole unit-containing side chains

“…The benzidine unit is considered to exhibit a two-step oxidationereduction profile as shown in Scheme 3. Similar process was previously suggested for triphenylamine unit-containing polymers [35,36]. In the case of the carbazole polymer 5c or 5d also, two carbazole pendant groups could form the corresponding dimeric unit 8b with release of two proton atoms in the electrochemical oxidation process via a cation radical 7b (Scheme 4) [37,38].…”

Conducting Polymers

“…Poly (PVTPA) [892,893] Synthesis: PVTPA was produced by free radical polymerization of 4-vinyltriphenylamine; the electrode was then coated with this polymer using an evaporation technique, and finally the electrooxidation results in the dimer form shown above [892]. PTPA was synthesized by the electrooxidative polymerization of triphenylamine in acetonitrile/TBAPF 6 [892].…”
