Electropolymerized Films of Macromeric Assemblies

Inorganic Chemistry, 1998
The polymer poly[4-(2-aminoethyl)styrene], prepared by living anionic polymerization, has been derivatized by amide coupling to [Ru(II)(vbpy)(2)(4-CO(2)H-4'-CH(3)bpy)](2+) (vbpy is 4-vinyl-4'-methyl-2,2'-bipyridine; 4-CO(2)H-4'-CH(3)bpy is 4-methyl-2,2'-bipyridine-4'-carboxylic acid).

Bulk electropolymerization of alkylpyrroles

Polymer, 1996
Abstract New larger-scale (10 g monomer in 500 cm 3 ) methods for the electropolymerization of alkylpyrroles in quantity have been developed. These methods offer the advantage of electropolymerization with fractionation in a single step. Galvanostatic, potentiostatic and potentiodynamic methods have been considered.

Electropolymerization on graphite fibers

Polymer Engineering & Science, 1978
AbstractThe electrodic polymerization on graphite fibers of a variety of monomers having different types of functional groups has been investigated. In addition to vinyl polymerization, some novel polymerizations of cyclic functional groups have been conducted under appropriate polymerization conditions.

Do Catechol Derivatives Electropolymerize?

Macromolecules, 2008
Several recent reports have claimed that catechol and its derivatives undergo electropolymerization when oxidized to form poly(o-phenylene)s. We demonstrate that the products of these electrochemical reactions are likely triphenylene derivatives rather than polymeric materials.

Electropolymerization potential—FMO relations

Journal of Polymer Science: Polymer Chemistry Edition, 1985
AbstractElectroinitiated polymerizations can be carried out by direct electron transfer if the anodic (Ep,a) and cathodic (Ep,c) potentials of monomers are known. Peak potentials of various halostyrenes were measured by cyclic voltammetry in acetonitrile for the first time.

Electropolymerization of naphthaleneamidinemonoimide-modified poly(thiophene)

Physical Chemistry Chemical Physics, 2011
The new polymer presents a p-doping process with anion exchange and its electrochemical reduction with cation exchange during potential cycling. Stored specific charges of 38 mAh g(-1) for the polymer reduction and 13 mAh g(-1) for its oxidation make the material very promising for fast charge/discharge batteries or specialised supercapacitors in which

The kinetics of electropolymerization

Synthetic Metals, 1991
Abstract During the potentiostatic polymerization of aniline, the periods of nucleation, growth of nuclei and stationary growth can be distinguished. The rate determining step is an oxidation reaction with a transfer coefficient α = 0.2 to 0.5 and E a = 57 kJ/mol.

Electropolymerization of phenylacetylene in acetonitrile

Journal of Polymer Science Part A: Polymer Chemistry, 2005
AbstractThe electrooxidation of phenylacetylene (PA) in acetonitrile (0.1 M in LiClO4) produced poly(phenylacetylene). The product was isolated, purified, and characterized. Spectroscopic data showed the trans structure of the polymer. A radical reaction mechanism was proposed in which the oxidation of PA led to the formation of a PA radical in ...

Electropolymerization mechanism of N-methylaniline

Synthetic Metals, 2006
A poly(N-methylaniline) (PNMA) film was obtained by chronoamperometry on tin oxide (TO) in dimethylformamide DMF containing 0.5 M sulphuric acid. The PNMA film formation was monitored by in situ UV–vis spectroscopy. A detailed electropolymerization mechanism and reaction pathway of N-methylaniline (NMA) is proposed based on mass spectroscopy (MS) and ...

Magneto-electropolymerization of conducting polypyrrole

Physica B: Condensed Matter, 1998
Abstract Magnetic fields were applied to the electropolymerization process of an organic conducting polymer polypyrrole. The magneto-electropolymerization was carried out in a cryocooler-cooled superconducting magnet and a Bitter magnet. The magnetic fields shifted the cathodic peak to more negative potentials in the cyclic voltammogram of the ...
