A novel ligand with two ester groups,two benzene rings and two carbox yl groups was synthesized. The composition and structure of the ligand were char acterized by the Fourier transform infrared spectroscopy(FT-IR) ,nuclear magnet ic resonance spectrum(NMR) and UV spectrometer. The rare-earth complex with the ligand and 1,10-phenanthroline(phen) was synthesized and structurally charact erized by FT-IR,TG and fluorescent spectrometer. The results showed that the no vel multicarboxyl ligand could efficiently transfer the energy to Eu3+ ions in t he complex and sensitize the luminescence of the rare earth ions,and the comple x could emit strong fluorescence of the rare earth ions. 展开更多
