modify electrodes for electrochemical asymmetric organic synthesis. Poly (N-camphorsulfonate substituted pyrrole) (PCPy) films on glassy carbon electrodes were stable and recognized chiral camphor sulfonate anion enatioselectively. The quantity of incorporated palladium in PCPy film- coated electrodes was well correlated with the electricity of PCPy polymerization and less than those in other N-substituted polypyrrole film electrodes. On PCPy film electrode incorporating palladium microparticles, the cathodic current for hydrogen evolution was observed.
