Abstract

Treatment of Ln(NO₃)₃·nH₂O with 1 or 2 equiv 2,2′-bipyrimidine (BPM) in dry THF readily afforded the monometallic complexes [Ln(NO₃)₃-(bpm)₂] (Ln = Eu, Gd, Dy, Tm) or [Ln(NO₃)₃(bpm)₂]·THF (Ln = Eu, Tb, Er, Yb) after recrystallization from MeOH or THF, respectively. Reactions with nitrate salts of the larger lanthanide ions (Ln = Ce, Nd, Sm) yielded one of two distinct monometallic complexes, depending on the recrystallization solvent: [Ln(NO₃)₃(bpm) ₂]·THF (Ln = Nd, Sm) from THF, or [Ln(NO₃) ₃(bpm)-(MeOH)₂]·MeOH (Ln = Ce, Nd, Sm) from MeOH. Treatment of UO₂-(NO₃)₂·6H₂O with 1 equiv BPM in THF afforded the monoadduct [UO₂-(NO ₃)₂(bpm)] after recrystallization from MeOH. The complexes were characterized by their crystal structure. Solid-state luminescence measurements on these monometallic complexes showed that BPM is an efficient sensitizer of the luminescence of both the lanthanide and the uranyl ions emitting visible light, as well as of the Yb^III ion emitting in the near-IR. For Tb, Dy, Eu, and Yb complexes, energy transfer was quite efficient, resulting in quantum yields of 80.0, 5.1, 70.0, and 0.8%, respectively. All these complexes in the solid state were stable in air.
