A luminescence mediator : An unusual lanthanide complex, exploiting a dendrimer and a ruthenium(II) complex as ligands, collects ultraviolet and visible light and exhibits luminescence in the near infrared region (see picture, N Blue, Ru brown, O red, C gray). In the absence of the ruthenium component the dendrimer is unable to transfer energy to the Nd III ion, even though it is directly coordinated to it.
