Influence of Structure and Reaction Conditions on Fluorescent Properties of Benzoic Acid Rare Earth Complexes
We synthesized a series of rare earth complexes with benzoic acid ramification containing different substitute groups or the same substitute group in different position; test the fluorescence property using fluorescence spectrometer of the complexes, and discussed the influence of different substitute group and the position of substitute group on the fluorescent properties of the rare earth complexes. The results showed that different substitute group and the position of substitute group on the benzene ring had important influence on the fluorescent properties of the benzoic acid rare earth complexes, when the other conditions were the same. The fluorescence effect of para-position ligand was better than ortho-position and meta-position ligand. For the benzoic acid complexes, their fluorescence intensity has relationship with the excellent absorption coefficient of the ligand and the high efficient ligand-to-trivalent rare earth ion energy transfer. Furthermore, when the ratio of Ln<3+>, ligand, phen was 1:3:1, the fluorescence properties of rare earth complex was the best.
