Journal ArticleDOI
Polypyrrole films containing metal complexes : syntheses and applications
TL;DR: In this article, a method to prepare polymer coatings on a carrier electrode based on electropolymerization of pyrrole and substituted pyrroles is described, and an overview of prospective applications is given.
Journal ArticleDOI
Correlation between permselectivity and chemical structure of overoxidized polypyrrole membranes used in electroproduced enzyme biosensors
TL;DR: In this paper, the authors investigated the permeability of common electroactive interferents in H 2 O 2 detecting amperometric biosensors through polypyrrole films overoxidized in aqueous solution by long-term electrolysis at low potential (+07 V vs Ag/AgCl) values in the order of 10-10 -10 -9 cm 2 s -1.

Electropolymerization of Pyrrole and Electrochemical Study of Polypyrrole. 3. Nature of “Water Effect” in Acetonitrile
Ming Zhou† and,Jürgen Heinze +1 more
TL;DR: In this paper, it was shown that water, a fairly strong base in acetonitrile, prevents the acid-catalyzed formation of a pyrrole trimer by capturing reaction-released protons.

Synthesis and Characterization of Electropolymerized Nanostructured Aminophenylporphyrin Films
Michael G. Walter,Carl C. Wamser +1 more
TL;DR: Porphyrins substituted at meso positions with aminophenyl groups undergo oxidative electropolymerization in a process analogous to the formation of polyaniline as mentioned in this paper.

Complexation of poly(pyrrole-EDTA like) film modified electrodes : Application to metal cations electroanalysis
Marie Heitzmann,Christophe Bucher,Jean-Claude Moutet,Eduardo Pereira,Bernabé L. Rivas,Guy Royal,Eric Saint-Aman +6 more
TL;DR: The selectivity of the molecular electrode materials can thus be subtly modulated upon playing on the accumulation time and on the pre-structuration of the complexing polymers as discussed by the authors.

Journal ArticleDOI
The electrodeposition of polypyrrole films from aqueous solutions
TL;DR: In this article, it was shown that the initial step in the formation of all polypyrrole films is a nucleation process and that all the electrochemical data resembles that for the nucleation and growth of a metal film.

Preparation and characterization of neutral and oxidized polypyrrole films
G.B. Street,T. C. Clarke,M. Krounbi,K. Keiji Kanazawa,Victor Y. Lee,P. Pfluger,J. C. Scott,G. Weiser +7 more
TL;DR: In this article, optical spectroscopy studies of both the electrochemically oxidized and the neutral polymer suggest the presence of highly mobile spins, consistent with the α,α' bonding in these polymers.
Journal ArticleDOI
Conducting polymer gas sensors
TL;DR: In this paper, solid-state semiconductor gas sensors based on organic sensor elements are reviewed and compared to metal-oxide devices in their sensitivity to toxic gases and their ability to operate at or near room temperature.

Determination of the Orientation of Adsorbed Molecules at Solid-Liquid Interfaces by Thin-Layer Electrochemistry: Aromatic Compounds at Platinum Electrodes
TL;DR: In this article, the limiting coverages of adsorbed molecules on smooth platinum electrodes were measured by linear potential scan voltammetry and potential-step chronocoulometry using thin-layer electrodes.

Determination of the acidity constants of some phenol radical cations by means of electron spin resonance
William T. Dixon,David Murphy +1 more
TL;DR: In this paper, the e.s.r. spectra of phenoxyl radicals were used to determine the pKa of the radical cations, which varied from −2.0 (phenol radical cation) to −0.8 (hydroquinone radicalcation).
