抄録

First-order and second-order decomposition kinetics have been determined electrochemically for the monocationic and dicationic forms of self-assembled monolayer (SAM) of Bfc-CO(CH₂)₇SH (1, Bfc = l’-biferrocenyl) on Au(111), respectively. In the mixed SAMs of 1 and octanethiol, the heterogeneous electron-transfer rate constant, k⁰, at 25 °C obtained by the dependency of the peak-to-peak separation (ΔE_p) on the scan rate for both Bfc⁺/Bfc⁰ and Bfc²⁺/Bfc⁺ couples increases with decreasing the surface coverage of 1. The k⁰ value for the Bfc²⁺/Bfc⁺ couple is slightly lower than that for the Bfc⁺/Bfc⁰ couple in the SAMs.
