摘要：

The reactivity of 4-bromophenyt modified glassy carbon electrode in the presence of 4-aminophenyl ferrocene was investigated. The presence of ferrocene moieties at the electrode surface was demonstrated by cyclic voltammetry and X-ray photoelectron spectroscopy. This presence could be explained either by the nucleophilic displacement of bromine of the 4-bromophenyl grafted groups by the amine of the ferrocene derivative or pi-pi stacking between the phenyl rings of the ferrocene derivative and the grafted phenylgroup.
