通过几步大分子反应过程，将双齿席夫碱(SB)配基键合在聚苯乙烯(PS)侧链，制得了双齿席夫碱配基功能化的聚苯乙烯 PS-SB.使大分子配体PS-SB 与 Eu(Ⅲ)离子螯合配位，制备了二元高分子-稀土发光配合物 PS-(SB)3-Eu (Ⅲ)，也以邻菲罗啉(Phen)为小分子第二配体，制备了三元高分子-稀土发光配合物 PS-(SB)3-Eu(Ⅲ)-(Phen)1.研究结果表明，键合的双齿席夫碱(SB)配基兼具有螯合配位与传能敏化双重功能，所制备的高分子-稀土配合物均能发射出很强的 Eu(Ⅲ)离子的特征荧光.大分子配体 PS-SB 本身具有强的荧光发射，但与 Eu(Ⅲ)离子配位后，其自身的荧光发射大为减弱，通过配合物分子内能量转移，可强烈地敏化 Eu(Ⅲ)离子发光.

Bidentate Schiff base (SB)ligand was bonded on the side of polystyrene (PS)via several steps of pol-ymer reactions,and the bidentate Schiff base ligand-functionalized PS,PS-SB,was obtained.The macromolec-ular ligand,PS-SB,was allowed to coordinate to Eu(Ⅲ)ion,resulting in the binary polymer-rare earth com-plex PS-(SB)3-Eu(Ⅲ).At the same time,with phenanthroline as second ligand,the ternary polymer-rare earth complex PS-(SB)3-Eu(Ⅲ)-(Phen)1 was also prepared.The experimental results show that the bond bidentate Schiff base ligand SB possesses the dual functions of coordination chelating and energy transfer-sensitization to-wards rare earth ion,and the prepared complexes can emit strong characteristic fluorescence of Eu(Ⅲ)ion.The macromolecular ligand PS-SB itself has strong fluorescence emission.However,after coordinating with Eu(Ⅲ) ion,the fluorescence emission of its own weakens remarkably,and strengthly sensitized the fluorescence emis-sion of Eu(Ⅲ)ion via the intramolecular energy transfer.
