In Situ Synthesis and Luminescence Characteristics of Complexes Europium with Schiff Base Ligands
The complexes of europium with two schiff base ligands [2-carboxybenzaldehyde- diethylenetriamine (1), 2-carboxybenzaldehyde-triethylenetetramine (2)] were in-situ synthesized. The formation of complexes was confirmed by the luminescence spectra. The luminescence spectra of two europium complexes were investigated in solid and in DMSO solution, respectively. The results show that two europium complexes exhibit low luminescence emission. And organic solvent DMSO could quench the luminescence of europium complexes.
