| Abstract: | The binary and ternary complexes of samarium,europium were synthesized with 2,4-dichlorophenoxyacetic acid as the first ligand,1,10-phenanthroline as the second ligand.According to elemental analysis,EDTA complexometric titration and TG-DTG,the molecular formula was determined to be RE(DCP)3 · H2O,RE(DCP)3phen(RE=Sm,Eu;DCP=2,4-Dichlorophenoxyacetic acid ion;phen=1,10-phenanthroline).Its structure was characterized by IR,UV;and the fluorescence spectra of the complexes were measured.The results indicated that RE(DCP)3phen had better thermal stability than RE(DCP)3 · H2O,Eu(DCP)3 · H2O and Eu(DCP)3phen had fluorescence performance. |
