Abstract: |
Six binary and ternary Tb (Ⅲ) complexes have been synthesized using the dextro-malic acid (L1), laevo-malic acid(L2) and racemic malic acid(L3) as the first ligand and 1,10-phenanthroline as the second ligand. Their properties were characterized by means of TG-DTG, IR spectra and fluorescence spectra. Study on the fluorescence spectroscopy of complexes indicated that all the complexes emit the strong characteristic fluorescence of Tb3+ ion. Chirality have small influence on the position change of complexes’ excitation peak and emission peak, but large on the fluorescence intensity. The fluorescence intensity of the ternary complexes is much stronger than that of the binary complexes. At the same time, the fluorescence intensity of the complexes of chiral malic acids is stronger than that of racemic malic complexes.
