Abstract

Abstract Effects of enantioselective interactions on redox reactions of chiral molecules were studied using Au single crystal electrodes modified with amino acids. The redox peak current densities of R(+)- or S(−)-N, N-dimethyl-1-ferrocenylethylamine on Au(111) modified with L- or D-homocysteine (L-/D-Hcy) depended on the combination of these chiralities. Hcy/Au(100) showed no dependence on redox peak current densities. The difference in the molecular arrangement of Hcy between Au(111) and Au(100) greatly affects enantioselective redox reactions at the electrode interface.
