Abstract

Recent developments in our understanding of the mechanisms of singlet excitation energy transfer (EET) in multichromophoric assemblies are reviewed. Particular emphasis is placed on the role of superexchange interactions involving the molecular framework linking the chromophores in the mediation of EET processes. Experimental measurements of the rates of EET in rigidly linked model bichromophoric compounds demonstrate that, under certain conditions, a through-bond interaction can dominate the energy transport process. High rates of EET in synthetic macromolecules are also observed, and the possible pathways of energy migration and trapping in these systems are outlined.
