Abstract
A binuclear complex has been synthesized having ruthenium (II) bis (2, 2′: 6′, 2 ″- terpyridine) terminals attached to a central 2, 2′-bipyrimidine unit via ethynylene groups. Cyclic voltammetry indicates that the substituted terpyridine is the most easily reduced subunit and the main chromophore involves charge transfer from the metal centre to this ligand. The resultant metal-to-ligand, charge-transfer (MLCT) triplet state is weakly ...
