Abstract We report the synthesis of a new pyrrole-substituted vitamin B 12 derivative functioning as a corrin monomer, its electrochemical copolymerization with pyrrole, and the potentiometric behavior of the resultant electrodes based on the corrin-doped polypyrrole film. Electropolymerization of the corrin monomer on a glassy carbon electrode and its redox properties were evaluated by cyclic voltammetry in acetonitrile in the presence of ...
