Electrochemical polymerization of 2-vinylpyrrole

Macromolecules, 1992
FTIR and electrical conductivity data of polymers obtained by electrochemical polymerization of 2-vinylpyrrole suggest aromatic coupling of the pyrrole rings of adjacent poly(2-vinylpyrrole) chains to form crosslinks. This polymer exhibits a electrical conductivity of ∼10 -5 S/cm.

Electric lithography by electrochemical polymerization

Applied Physics Letters, 2005
We demonstrate a lithographic technique, electric lithography, in which conductive patterns on a mask are transferred to a substrate by applying an electric field to locally configure a resist layer sandwiched between the patterns and the substrate. Proof-of-concept pattern transfer experiments were carried out through electrochemical polymerization of

Electrochemical and chemical polymerization of indole

International Conference on Science and Technology of Synthetic Metals, 1994
Summary form only given. Electrochemical oxidation of indole, C/sub 8/NH/sub 7/, in non aqueous media like solutions of LiC1O/sub 4/ or LiBF/sub 4/ dissolved in acetonitrile, leads to the formation of polyindole, an air stable conducting polymer which exhibits interesting electrochromic properties.

Electrochemical polymerization of 2-methoxynaphthalene

Synthetic Metals, 2003
Electropolymerization of 2-methoxynaphthalene in TBAPF6-ACN and characterization of the formed film were studied by cyclic voltammetry (CV), electrochemical quartz crystal microbalance (EQCM), Fourier transform infrared spectroscopy (FT-IR) and by scanning electron microscopy (SEM).

Electrochemical reduction of polymeric carbon

Electrochimica Acta, 1981
It was found that the electrochemical reduction of poly (tetrafluoroethylene) with lithium amalgam leading to the mixture of polymeric carbon and lithium fluoride as solid product is followed by a consecutive electrochemical reaction via a polymeric anion radical, [(Cn)−]m.

Electrochemical polymerization of 9-fluorenone

Journal of Electroanalytical Chemistry, 2004
Abstract Electrochemical polymerization of 9-fluorenone, FO, was studied in CH2Cl2 solution with tetrabutylammonium tetrafluoroborate, TBABF4, as the electrolyte, via constant potential electrolysis, CPE. Prior to CPE, the redox behavior of FO was investigated in the same solvent/electrolytic medium using cyclic voltammetry, CV.

Electrochemical Polymerization of Dithienylbenzene and Dithienylpyridine

Journal of Macromolecular Science: Part A - Chemistry, 1987
Abstract 1,4-Bis(2-thienyl)benzene (T14B), 2,5-bis(2-thienyl)pyridine (T25P), and 2,6-bis(2-thienyl)pyridine (T26P) were electrochemically polymerized. The conductivity of poly-T14B, poly-T25P, and poly-T26P was 1.7 × 10−1, 2.6 × 10−8, and 1.2 × 10−7 S/cm, respectively.

Electrochemical polymerization of biphenyl in acetonitrile

International Conference on Science and Technology of Synthetic Metals, 1994
Summary form only given. Details of the electropolymerization process of biphenyl on platinum electrode were studied. It is shown that the presence of water in the solution has a strong effect on the formation of polyphenylene. The influence of biphenyl concentration, solvent, rotating speed of the electrode and the upper limit of the electrode ...

Electrochemical Polymerization of Methylene Green

Chinese Journal of Chemistry, 2001
AbstractThe electrochemical polymerization of methylene green has been carried out using cyclic voltammetry. The electrolytic solution consisted of 4° 10−3 mol/L methylene green, 0.1 mol/L NaNO3 and 1 × 10−2 mol/L sodium tetraborate with pH 11.0. The temperature for polymerization is controlled at 60°C. The scan potential is set between −0.2 and 1.2 V (

Electrochemical polymerization of substituted thiophenes

Makromolekulare Chemie. Macromolecular Symposia, 1989
AbstractThe electrochemical polymerization of 3‐(n‐butyl)thiophene and of several 3‐ or 3,4‐ substituted α, α'‐terthienyls is described and the properties of the conducting polymers are discussed. A solution in acetonitrile of the terthienyl substituted by a potassium propylsulfonate group is polymerizable as such, and the polymer is the first proven ...
