| Abstract: | Using pyridine - 2,6 - dicarboxylic acid as starting material, a novel ligand dimethyl 4 - （2 - acetyl - 3 - oxobutyl） pyridine -2,6 -dicarboxylate was synthesized. The ligand was characterized by IR and 1 HNMR. Moreover, its corresponding Tb（III） and Eu（III） complexes were also prepared. These complexes were characterized by elemental a- nalysis and IR. The photoluminescence properties of Eu2 （L） 3 · 2H20 and Tb2 （ L）3 · 3H2O were investigated by fluores- cence spectra. |
