Next generation of (polyazine)ruthenium(II) complexes
The synthesis and characterization of a new, highly luminescent complex of ruthenium and 2,3-bis(2-pyridyl)pyrazine (dpp) of the type Ru(dpp)/sub 3//sup 2 +/ are reported. Comparison of the intensity of the electronic absorption and emission spectra of this complex with that of Ru(bpy)/sub 3//sup 2 +/ where bpy = 2,2'-bipyridine, the complex so often used to study capture, storage, and utilization of solar energy, suggests that the complexes have similar luminescence quantum yields. The presence of three bidentate remote binding sites in Ru(dpp)/sub 3//sup 2 +/ raises the possibility of preparing polymetallic clusters with appreciable excited-state lifetimes to generate systems capable of photocatalyzing multielectron reactions. 23 references, 2 figures.
