Building blocks for polymetallic ruthenium(II) and osmium(II) polypyridine luminophores
Abstract
Three novel, mixed-ligand complexes of ruthenium and osmium are prepared1; the key example [Ru(bpy)2bpaH](PF6)2[bpy = 2,2′-bipyridine; bpaH = bis(picolyl)amine]1 bears a ‘dangling’ pyridine ligand according to X-ray crystallography and has a luminescence lifetime comparable with that of [Ru(bpy)3]2+.
