The shape of metallosupramolecular assemblies

This is the authors' abstract. We don't add key points for this paper.

Despite original doubts on its feasibility, the control of the stereochemistry in ligand-bridged oligonuclear assemblies based on tris(bidentate) components has seen considerable progress in the last two decades, and differences have been observed in the physical characteristics of stereoisomers of such species. This retrospective review examines the background to this "stereochemical problem" and shows how the control of the stereochemical integrity of dinuclear and trinuclear ligand-bridged complexes has been utilised in studies of intramolecular electron transfer within the oligonuclear assemblies, and in probing the sequence- and structure-selectivity of the interaction of these species with nucleic acids.
