[Extract] Polymetallic supramolecular assemblies have been the subject of attention because of their potential application to light-harvesting and light-activated devices. However, the electronic and spatial requirements for effective intercomponent energy transfer within these assemblies are not well understood, and ligand design becomes pivotal to any study addressing such issues.
We have recently reported the synthesis of a variety of bifunctional ligands incorporating rigid alicyclic spacers and their reaction with appropriate metal centers to provide homodinuclear complexes. The synthesis of analogous heterodinuclear complexes presents a significant challenge due to the preferential formation of homodinuclear byproducts, and examples of coupling procedures for selective formation of mixed-metal systems are limited and relatively recent.
