摘要
A dithiolate-bridged diiron complex containing succinimide ester has been grafted on glassy carbon electrodes modified with either amine or aminophenyl groups. Covalent attachment of the complex through amide binding is confirmed by the linear dependence of the reduction peak current on the voltammetric scan rate. Attachment using the aminophenyl-modified electrode leads to better behaved cyclic voltammograms. The effect of addition of acid on the voltammetric response is also reported.
