含稀土铕配合物三维有序大孔材料的制备及其荧光性能

Preparation and Luminescence Properties of Three-Dimensionally Ordered Macroporous Materials Loaded with Rare Earth Eu(III) Complex

采用物理吸附的方法将稀土配合物嵌入三维有序大孔聚合物材料的孔内,组装了发光性能良好的含邻菲罗林-铕配合物的三维有序大孔聚合物材料(3DOM/Eu(Phen)2)。并通过扫描电镜、红外光谱和荧光光谱对3DOM/Eu(Phen)2组装体进行了表征。结果表明:组装体的结构保持了三维有序大孔材料的结构特征,在紫外灯的照射下,发出稀土离子的特征谱线,与纯配合物相比,其激发光谱发生蓝移,荧光寿命延长。

Novel three-dimensionally ordered macroporous polymeric materials loaded with rare earth Eu （Ⅲ） complex （3DOM/Eu（Phen）2） was prepared by means of physical absorption. The 3DOM/Eu（Phen）2 self-assembly was characterized by SEM, FT-IR and luminescence spectroscopy. SEM images confirmed typical 3DOM structure in the assembly. The emission spectrum showed distinctive Eu^3＋ absorption and the excitation spectrum showed blue shift compared to that of neat rare earth complex Eu（Phen）2. The decay curve indicated that the 3DOM/Eu （Phen）2 materials have longer luminescence lifetime than Eu （Phen） 2.
