Figure 3. Electrochemical studies of NHC-based films.

Figure 3

(a) Cyclic voltammetry (background subtracted) of 3c-based films showing asymmetric electron transfer (scan rate 1 Vs−1). (b) Tafel plot. (c) Cyclic voltammogram measured at 200 Vs−1. (d) Restructuring of the film on oxidation to give a more ordered film with faster electron transfer. (e) Electron transfer rates of 3c-based films compared with films from thiols of similar chain length. (f) Linear dependence of current density versus scan rate, confirming that the ferrocene conjugate is immobilized on the surface.
