Take the stepping stones : Electrons are exchanged between both termini of α‐helical peptide self‐assembled monolayers (SAMs) on gold by a hopping mechanism with the amide groups as hopping sites (see picture). The rate constant of 0.45 s −1 for the 64‐mer peptide is significantly high for electron transfer through dielectric organic materials.
