Abstract
A series of photoactive complexes of [RuIIbis(bipyridyl){2-(4-methylpyridin-2-yl)benzo[d]-X-azole}](PF6)2 (X = N–CH3, 1; S, 2; or O, 3) have been synthesized and fully characterized by proton and 13C NMR spectroscopy and UV/Vis spectroscopy. The X-ray structure of 1 is also reported. The electrochemical behavior and the photophysical properties of 1–3 have been investigated. Cyclic voltammetry (CV) reveals the presence of three consecutive one-electron reduction processes and a single one-electron oxidation process that are chemically and electrochemically reversible. In all cases, electrogenerated chemiluminescence (ECL) has been observed in the presence of the co-reactant tri-n-propylamine (TPA). An analogue of 1 has been synthesized, [RuIIbis(bipyridyl){2-(4-methylpyridin-2-yl)benzo[d]-X-azole}](PF6)2 [X = N(CH2)5CO2H, 4], it has been coupled with bovine serum albumin (BSA), and its photophysical properties investigated.
