Electrochemical Saccharide Recognition by a Phenylboronic Acid-Terminated Redox Active Self-Assembled Monolayer on a Gold Electrode

Phenylboronic acid-terminated viologen-carrying alkyl disulfide (1) and a reference compound 2 were designed and synthesized. Self-assembled monolayers of 1 on gold electrodes were found to function as a highly sensitive saccharide sensor in aqueous solution.
