The length of the peptide spacer determines the rate of electron transfer from the gold surface to the ferrocenoyl group in self‐assembled monolayers (see diagram) of a series of ferrocenoyl‐oligoproline‐cystamines [Fc‐Pro n ‐CSA] 2 ( n =0–6), as determined from cyclic voltammetric experiments. The redox‐labeled peptides form well‐behaved and stable monolayers on gold.
