摘要：

Five novel lanthanide (Eu3+, Tb3+, Gd3+, Sm3+ and Dy3+) complexes with 2, 2'-bipyridine- N, N'-dioxide (bipyO(2)) were synthesized and characterized by elemental analysis, IR spectrum. The triplet state energy of bipy O-2 was determined to be 22275 cm(-1) with the phosphorescence spectrum of bipy O-2 and its gadolinium complex. The photophysical properties of these complexes indicated that the triplet state energy of the ligand is suitable for the sensitization of the luminescence of Eu3+, Tb3+, Sm3+ and Dy3+, especially of Tb3+.
