A new bridging ligand for the synthesis of luminescent polynuclear Ru(II) and Os(II) polypyridine complexes
Abstract
A new bridging ligand has been synthesized by reacting 4-hydroxy-2,2′-bipyridine with a Ru(II)-coordinated 4-bromo-2,2′-bipyridine; this bridging ligand allowed the synthesis of polynuclear Ru(II) complexes that display the same luminescence properties as [Ru(bpy)3]2+.
