摘要

Europium(III) and terbium(III) complexes have been prepared using the ligands 2-(4,5-dihydro-1,3-oxazol-2-yl)-phenol (HL1) and 2-(4,5-dihydro-1,3-thiazol-2-yl)phenol (HL2) in yields ranging between 74 and 100%. Metal-toligand ratios of 1:3 and 1:4 can be achieved, giving rise to compounds with the formulae [Ln_2(L)_6] and NR_4[Ln(L)_4], Ln = Eu, Tb. Recrystallisation of the complexes from DMSO resulted in the formation of octanuclear complexes [Na_2(Ln(L1)_3)_2(CO_3)(DMSO)_2]_2 held tightly together by carbonate ions that have been formed from CO_2 from the atmosphere. Five structures have been determined, showing a bidentate binding mode of the ligand through the phenolate oxygen and the nitrogen atom of the five-membered ring. Most terbium compounds show bright luminescence upon excitation with near-UV radiation, with quantum yields of 16% to 79%. Strong emission is observed for NBu4[Eu(L1)4] and NEt_4[Eu(L_2)_4] with quantum yields of 43% and 20%, respectively.
