| Popis: |
Benzoic acid(BA) ligand was bonded on the side chains of polysulfone(PS) via a polymer reaction and obtained aryl carboxylic acid-functionalized polysulfone PSBA.The secondary complex PS-(BA)3-Tb(Ⅲ),the ternary complexes PS-(BA)1-Tb(Ⅲ)-(Phen)2 and PS-(BA)1-Tb(Ⅲ)-(Phen)3 were prepared by the coordination of Tb(Ⅲ) ion and PSBA using PSBA as a macromolecular ligand and phenanthroline(Phen) as a smaller ligand.The chemical structures of the complexes were characterized by FTIR and UV absorption spectra,and their florescence emission characters were investigated.The investigation results show that both the secondary complex and ternary complexes formed by using PSBA as a macromolecular ligand can emit the strong characteristic fluorescence of Tb(Ⅲ) ion,which indicate the BA bonded on the side chains of PSBA can effectively sensitize the fluorescence emission of Tb(Ⅲ) ion.In comparison with the secondary complex PS-(BA)3-Tb(Ⅲ),the ternary complexes with Phen as the second ligand have higher florescence emission intensity. |
