A new acceptor polypyridinic ligand functionalized with a quinone fragment is reported. The ligand, dipyrido [3, 2-a: 2′, 3′-c]-benzo [3, 4]-phenazine-11, 16-quinone, Nqphen, was synthesized by condensation of 1, 10-phenanthroline-5, 6-dione and 2, 3-diamino-1, 4- naphthoquinone. The syntheses of two rhenium complexes with this ligand are also reported.
