A novel multi-branched ligand with multiple ester groups, multiple benzene rings and multiple carboxyls was synthesized. The composition and structure of the ligand were characterized through the Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectrum (1H NMR) and UV spectrometer. The composition and fluorescence properties of rare earth complexes with the ligand and 1,10-phenanthroline (phen) were researched via FT-IR, EA and fluorescent spectrometer. The results presented that the resulting complex had strong characteristic fluorescence spectrum of the rare earth ions, which was attributed to the synergistic effects of the ligand, phen, and rare earth ion.
