Abstract
AbstractMolecular assemblies of surface‐confined heterometallic molecular dyads (SURHMDs) composed of optically rich and redox‐active Fe(pytpy)2·2PF6 (Fe‐PT), Ru(pytpy)2·2PF6 (Ru‐PT) and Os(pytpy)2·2PF6 (Os‐PT) pytpy = 4′‐(4‐pyridyl)‐2,2′:6′,2″‐terpyridyl] complexes are fabricated via bottom‐up approach on SiOx based solid supports. Pairing of the two different metal‐organic complexes at a single platform results in significant enlargement of the optical window (λ = 400–800 nm), which can be of interest for potential applications. The use of the Cu‐based linker ensures intramolecular electronic communication between these complexes. In addition, SURHMDs are electrochemically stable under large numbers of read‐write cycles (103) and exhibit multiple redox states at relatively low potentials (<1.2 V). Moreover, an electrochemical input at controlled potentials creates a mixed‐valence multicomponent system.
