合成了一种作为核的带有多苯环联结结构、多羰基、双羧基的新型稀土配合物,对配合物的红外光谱,固相核磁碳谱和荧光光谱进行了研究。红外光谱表明所制备的新型配体与稀土Eu3+进行了配位,而邻菲啰啉中的氮原子也与稀土离子进行了成键。所制备的配合物的荧光光谱表明配合物具有优异的荧光特性,同时配体与稀土离子间具有较好的能量转换性能。 A novel rare earth complex with a benzene ring, a polycyclic carbonyl group and a dicarboxy group as a core was synthesized. The infrared spectra, solid-state NMR spectra and fluorescence spectra of the complexes were studied. Infrared spectra showed that the new ligands prepared were coordinated with rare earth Eu3 +, while the nitrogen atoms in ortho-phenanthroline were also bonded with rare earth ions. Fluorescence spectra of the prepared complexes show that the complexes have excellent fluorescence properties, while the ligand and rare earth ions have better energy conversion performance.
