Abstract

Interfacial electron transfer at bis(tpy)–iron(II) complexes (tpy=2,2′:6′,2′′-terpyridine) on Si(111) electrodes was investigated by using four types of surface-anchor terpyridine ligands. Despite the greater distance, electron transfer between the bis(tpy)–iron(II) unit and the electrode is accelerated in surface-anchor ligands with an additional phenylene group.
