摘要

通过大分子反应将苯甲酸(BA)键合在聚苯乙烯(PS)侧链

制得芳羧酸功能化的聚苯乙烯PSBA。以PSBA为大分子配基

以邻菲啰啉(Phen)为小分子配体

与Tb(Ⅲ)离子配位

分别制备了二元配合物PS-(BA)

-Tb(Ⅲ)与三元配合物PS-(BA)

-Tb(Ⅲ)-(Phen)

及PS-(BA)

-Tb(Ⅲ)-(Phen)

采用红外光谱(FTIR)和紫外吸收光谱(UV) 对配合物进行了表征

深入研究了配合物(溶液与薄膜)的荧光发射性能。研究结果表明

大分子配基PSBA与Tb(Ⅲ)离子所形成的二元或三元高分子-稀土配合物均能发射出很强的Tb(Ⅲ)离子特征荧光

即键合在PSBA侧链的配基BA能有效地敏化Tb(Ⅲ)离子的荧光发射。与二元配合物相比较

以小分子Phen为第二配体所形成的两种三元配合物具有强度更高的荧光发射。

Abstract

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)

-Tb(Ⅲ)

the ternary complexes PS-(BA)

-Tb(Ⅲ)-(Phen)

and PS-(BA)

-Tb(Ⅲ)-(Phen)

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)

-Tb(Ⅲ)

the ternary complexes with Phen as the second ligand have higher florescence emission intensity.
