ABSTRACT
Rare earth (Eu)-polymer ternary complexes were synthesized using copolymer of 4-vinyl pyridine-methyl acrylate as ligand, and using phen and bipy as coordination ligand. The compositions of the complexes were characterized by FTIR and elemental analysis. The photophysical process of photoluminescence of the complexes were characterized by FTIR and elemental analysis. The photophysical process of photoluminescence of the complexes was discussed more fully by UV spectra and fluorescence spectra. The experiment result shows that the copolymer of 4-vinyl pyridine can coordinate into rare ions directly by nitrogen atom in the pyridine ring. When small ligand reacts with coordination, the fluorescence intensity of the complexes increases greatly because of stronger intermolecular energy transfer.
