Towards the development of polynuclear electron reservoirs containing terpyridine metal complexes

The preparations of multinuclear supramolecules assembled from 1′,1‴-bis(terpyridyl)biferrocene redox-active subunit with Ru(II) metal centers are described. The appreciable variations detected in the Fe2+/Fe3+ oxidation potentials indicate that there is an interaction between the spacer and terminal ferrocenyl moieties. The binuclear bis(terpyridyl)biferrocene appears to be promising bridge which can ensure fast and quantitative transfer of energy within the array.
