摘要
详细研究了10-二茂铁-1-癸硫醇（HSC10Fc）在金基底上形成的自组装单分子膜的电化学行为，发现HSC10Fc在金基底上能形成稳定的自组装膜，并且在0．1mol／L的HCIO4溶液中表现出可逆的氧化还原行为，但其氧化还原峰的峰形和峰位极易受溶液中阴离子种类和浓度的影响．考察了二茂铁自组装膜及通过后置换形成的二茂铁硫酸／十二烷基硫醇混合膜在混合电解液中的电化学行为，直接比较了两种不同阴离子与二茂铁阳离子的结合能力，
Ferrocenylalkanethiol (HSC10Fc) can be self-assembled into a stable and repro-ducible monolayer on gold. The self-assembled monolayer(SAM) showed a reversible redoxbehavior in 0. 1 mol/L HClO4 solution, while its voltammetric properties was influenced byboth type and concentration of the supporting electrolytes. On the basis of 'ion pair' effect,a detailed experimental investigation was performed to evaluate the role of type and concen-tration of the different anions in determining the shapes and positions of the redox peaks. Atthe same time, the mixed monolayer of HSC10 Fc with HSC11 CH3 was prepared, whichshowed varied electrochemical behavior comparing to the pure monolayer. However, the ion-pair effect was the same as the pure monolayer-
