Abstract
The coordination properties of the tridentate ligand 2,2′:6′,2″-terpyridine make it an ideal structural unit to incorporate into monomers to be used for the assembly of coordination polymers. The electronic properties of metal complexes may be subtly controlled by the incorporation of electron withdrawing or electron releasing substituents upon the 2,2′:6′,2″-terpyridine. The synthesis of a range of such ligands is described, and a detailed study of the electronic and solution properties of their homoleptic and heteroleptic ruthenium(II) complexes is reported. Linear coordination oligomers and polymers are readily prepared by the use of bis(2,2′:6′,2″-terpyridine) ligands as linkers, and the synthesis of materials derived from two such linkers is reported. The electronic properties of these compounds may be controlled by the introduction of suitably substituted terminator ligands. The synthesis of a novel tris(2,2′:6′,2″-terpyridine) ligand is reported which forms an extended three-dimensional coordination polymer. The preparation and characterisation of a single triruthenium unit from such a polymer is reported.
