Abstract

The tetradentate ligand 4,4′-bis(trifluoromethyl)-2,2′-bipyridine-6,6′-dicarboxylic acid (H₂1) and three corresponding anionic rare earth complexes [RE(1)₂]⁻ (RE = Y, Tb, Dy) were synthesized. The terbium and dysprosium complexes show lanthanoid-centered luminescence in aqueous solution, as well as paramagnetically enhanced longitudinal magnetic relaxation of the ¹⁹F nuclei.
