Phenol electropolymerization in acid medium

Makromolekulare Chemie. Macromolecular Symposia, 1987
AbstractAn overview is given of phenol electro‐polymerization in oxalic acid media, as a method of corrosion protection for Fe substrates. The work focuses on the electrical and/or chemical parameters of the system which mainly determine the growth and/or corrosion resistance of the organic‐inorganic films thus obtained.

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).

Naphthobipyrrole: Versatile Synthesis and Electropolymerization

The Journal of Organic Chemistry, 2010
A facile synthetic route to a new polycyclic pyrrole derivative, 3,8-diethyl-1,10-dihydro-benzo[e]pyrrolo[3,2-g]indole (1), is reported. This annulated bipyrrole acts as a monomer for electropolymerization and forms an electrochromic conducting polymer (poly1) when electrooxidized at low potentials (0.4 V vs Ag/Ag(+)) in acetonitrile.

More on the electropolymerization of styrene

Polymer, 1986
Abstract The cathodic reduction of styrene in acetonitrile and tetra-n-butylammonium tetrafluoroborate is discussed. A well defined voltammetric wave was obtained at Ep = −2.8 V and its study reveals irreversible electron transfer as the first step in the electrochemical reaction.

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 ...

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.

The mechanisms of pyrrole electropolymerization

Chemical Society Reviews, 2000
Over the past twenty years, polypyrrole has appeared as the most extensively studied conducting polymer. However, despite the volume of work already done in this area, there has been little focus put on the mechanism of polypyrrole synthesis, especially concerning the most efficient method, electropolymerization.

Deposition of Enzymes by Electropolymerization

1991
A significant problem in the large scale application of enzymes and other proteins for the development of microscale biosensors is the difficulty in fabricating uniform and reproducible coatings containing the active protein (Wingard, 1990b). With emphasis on biosensor miniaturization as well as the utilization of many types of biological materials in ...
