Exciton-like energy collection in an oligothiophene wire end-capped by Ru- and Os-polypyridine chromophores

摘要

Ru(II) and Os(II)-polypyridine termini are linked by a quinquethiophene bridge (the inter-metal separation is ca.1.9 nm) wherein excitation energy flows into the luminescent Os-based unit by way of a conductive level.Transfer of excitation energy between terminal chromophores of wire-like molecular arrays is well documented.
