Electrochemistry of mesoporous organosilica of MCM-41 type containing 4,4-bipyridinium units: voltammetric response and electrocatalytic effect on 1,4-dihydrobenzoquinone oxidation

Study of the electrochemistry of a novel organic-inorganic material in which 4,4-bipyridinium units (BP) are covalently attached to the walls of a periodic mesoporous organisilica (PMO) of the MCM-41 type is reported. It was observed that the electrochemical response of regular mesoporous organosilica of the MCM-41 type containing bipyridinium units covalently attached vary significantly for as-synthesized material, BP@PMO.
