| 英文摘要 | 4-aminobenzylphosphonic acid (4-abpa) was covalently grafted on a glassy carbon electrode (gce) through two types of reaction mechanisms viz. amine oxidation and the kolbe-like reaction during the electrooxidation process in 0.1 m kcl aqueous solution. two irreversible oxidation peaks were observed at about 0.75 and 0.90 v in cyclic voltammograms between 0.5 and 1.1 v. x-ray photoelectron spectroscopy (xps) shows the presence of two types of n 1s environment after oxidation of 4-abpa on the gce surface. the quantum chemistry calculation proves that both of the nh2 and ch2 groups in 4-abpa molecule can perform the oxidation reaction in turn. from this, we found and substantiated that the kolbe-like reaction of benzylphosphonic acid group in 4-abpa molecule can take place in aqueous solution.
