Linker rectifiers induce directionality of interfacial electron transfer suitable for multi-electron reactions at electrode surfaces. The linkers have a terpyridyl group that can covalently bind Mn as in a well-known water oxidation catalyst and an acetylacetonate group that allows attachment to TiO2 surfaces. The appropriate choice of the sense of the amide linkage suppresses back-electron transfer by shifting the transport channel away from the Fermi level.
