Assembly of heterogeneous molecular dyads
Adv. Funct. Mater. 23, 4227 (2013)
Molecular assemblies of surface-confined heterometallic molecular dyads (SURHMDs) composed of optically rich and redox-active mettaloo-organic, terpyridyl-based complexes are fabricated via bottom-up approach on SiOx based solid supports. Pairing of the two different metalorganic complexes at a single platform results in significant enlargement of the optical window (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 (10 3 ) 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.
