Diruthenium ethynyl complexes 1-3 (1: 1,5-dithia-s-indacene-4,8-dione; 2: 4,8-diethoxybenzo[ 1,2-b:4,5-b']dithiophene; 3: 4,8-didodecyloxybenzo[ 1,2-b:4,5-b']dithiophene) have been synthesized by incorporating the respective conjugated heterocyclic spacer and characterized by NMR and elemental analysis.The effects of bridge ligands' properties on electronic coupling between redox-active ruthenium terminal groups were investigated by electrochemistry,UV/vis/near-IR and IR spectroelectrochemistry combined with density functional theory (DFT) and ...
