摘要：

Two stable 8-quinolinolate complexes of ruthenium(II), [Ru(bpy)(Q)]ClO4 and [Ru(taP)2(Q)]ClO4 [bpy = 2,2'-bipyridine, Q = 8-quinolinolate anion, tap = 2-(m-tolylazo)pyridine] have been synthesized. The complexes are diamagnetic and show strong absorption near 1100 cm-1 in the IR spectra due to the presence of ClO4-. In acetonitrile solution they behave as 1:1 electrolytes. The complexes display intense absorption bands in the visible region (400-700 nm) which are assigned to MLCT transitions. The formal potential (E298(0)), determined cyclic voltammetrically for the ruthenium(II)-ruthenium(III) oxidation, is 0.48 V vs SCE for [Ru(bpy)2(Q)]+. The same oxidation takes place irreversibly at 1.00 V vs SCE (E(pa) value) in the case of (Ru(tap)2(Q)]+. Reductions of the bound bpy and tap ligands are also observed.
