Abstract

The syntheses and characterisation of a series of mononuclear and dinuclear ruthenium polypyridyl complexes based on&nbsp;the bridging ligands 1,3-bis-[5-(2-pyridyl)-1<i>H</i>-1,2,4-triazol-3-yl]benzene, 1,4-bis-[5-(2-pyridyl)-1<i>H</i>-1,2,4-triazol-3-yl]benzene, 2,5-bis-[5-(2-pyridyl)-1<i>H</i>-1,2,4-triazol-3-yl]thiophene, 2,5-bis-[5-pyrazinyl-1<i>H</i>-1,2,4-triazol-3-yl]thiophene are reported. Electrochemical studies indicate that in these systems, the ground state interaction is critically dependent on the nature of the bridging ligand and its protonation state, with strong and weak interactions being observed for thiophene- and phenylene-bridged complexes, respectively. <p>
