Emissive cyanide-bridged bimetallic compounds as building blocks for polymeric antennae

A series of cyanide-bridged bimetallic compounds of the general formula [Ru(L)(bpy)(μ-NC)(M)]2-/-/2+ (L = tpy, 2,2′-6′, 2′′-terpyridine, or tpm, tris(1-pyrazolyl)methane, bpy = 2,2′-bipyridine, M = RuII(CN)5, Os III(CN)5, OsII(CN)5, Ru II(py)4(CN), py = pyridine) have been synthesized and fully char...
