Abstract
New functional electrode materials, based on polypyrrole, were prepared by potentiostatic electro-copolymerization of pyrrole with two different pyrrole monomers, functionalized with carboxylic group: 3-(1-pyrrolyl)-propanoic acid and 4-oxo-4(1H-pyrrole-3-yl)butanoic acid. The properties of the polymeric electrode materials depend mainly on the synthesis method, monomers ratio, reaction time, and the composition of the supporting electrolyte. The obtained materials were characterized by Fourier transform infrared spectroscopy and cyclic voltammetry measurements. The poly-(pyrrole-co-beta-(1pyrrolyl) propanoic acid) copolymer, deposited on the surface of a glassy carbon electrode, was used as anchor for covalent immobilization of Toluidine... (More)
New functional electrode materials, based on polypyrrole, were prepared by potentiostatic electro-copolymerization of pyrrole with two different pyrrole monomers, functionalized with carboxylic group: 3-(1-pyrrolyl)-propanoic acid and 4-oxo-4(1H-pyrrole-3-yl)butanoic acid. The properties of the polymeric electrode materials depend mainly on the synthesis method, monomers ratio, reaction time, and the composition of the supporting electrolyte. The obtained materials were characterized by Fourier transform infrared spectroscopy and cyclic voltammetry measurements. The poly-(pyrrole-co-beta-(1pyrrolyl) propanoic acid) copolymer, deposited on the surface of a glassy carbon electrode, was used as anchor for covalent immobilization of Toluidine Blue (TB), by coupling its aromatic amino group (position 3) with the carboxylic groups existing on the modified electrode. The covalent binding of TB onto the functionalized electrode surface results in a stable modified glassy carbon electrode, exhibiting a better electrochemical activity than that corresponding to poly-TB, obtained by TB electropolymerization on the same electrode surface.
