Several disparate systems have been examined as putative molecular-scale wires able to conduct charge over relatively long distances under illumination. The key feature of such systems concerns the level of electronic coupling between the terminals, which are themselves formed from photoactive ruthenium(II) or osmium(II) poly(pyridine) complexes. Photophysical properties have been recorded in fluid solution and, where appropriate, the mechanism for long-range electron exchange has been clarified. In order to ascertain the importance of excited states localized on the organic framework, the photophysical properties of the free ligands have also been determined. The ligands bind zinc(II) cations in solution and thereby affect the absorption and emission spectra. This allows determination of the binding constants.
