摘　　要：A Schiff base ligand was synthesized by condensating 5-bromosalicylaldehyd with ethylenediamine and several rare earth complexes,such as La(Ⅲ)、Ce(Ⅲ)、Nd(Ⅲ) were synthesized.The compositions and structures of the ligang and its complexes were characterized by the elemental analyses,thermal analyses,IR spectra,UV spectra,1H NMR and molar conductivity.The fluorescence property and dismutation to O-2 free radical were also investingated.A Schiff base ligand was synthesized by condensating 5- bromosalicylaldehyd with ethylenediamine and several rare earth complexes,such as La（III） ,Ce（III） ,Nd（ III ） were synthesized.
