Abstract

Chiral polyaniline electrodes were prepared by the magneto- electropolymerization (MEP) method. Cyclic voltammograms (CVs) of l-ascorbic acid (L-AA), d-isoascorbic acid (D-AA), and l-3-(3,4-dihydroxyphenyl)alanine were measured on the MEP polyaniline electrodes and their electrode reactions were electrocatalytic. The CV peak currents varied depending on the chirality of the polyaniline and the optically active species, while the peak potentials were independent of the chirality. The CVs of L-AA and D-AA were also measured on a Pt electrode in a (-)-camphor-10-sulfonic acid supporting electrolyte solution, and the chiral behavior was observed in the peak potentials. It is considered that the electrocatalytic process is responsible for the chiral electrochemical behavior on the polyaniline electrodes.
