Bis(tridentate) Iron(II) Complexes with a Cyclometalating Unit: Photophysical Property Enhancement with Combinatorial Strong Ligand Field Effect

A series of bis(tridentate) cyclometalated oligopyridine complexes [FeII(C∧N∧N)(L)]+ have been synthesized via the reactions of [FeII(C∧Npy∧Npy)Br(PMe3)2] (1, HC∧Npy∧Npy = 6-(phenyl)-2,2′-bipyridin...
