The Synthesis,Characterization and Photophysical Properties of Binary and Ternary Rare Earth Complexes with N-Phenylanthranilic Acid and 1,10-Phenanthroline

Some novel binary and ternary complexes of rare earth(Gd, Eu ,Tb) with N Phenylanthranilic acid and 1,10 Phenanthroline were synthesized by homogenous precipitation and their compositions were characterized by elemental analysis, IR spectra and UV Vis spectra. The triplet state energies of N Phenylanthranilic acid was determined to be 24 330 cm -1 with the phosphorescence spectra of its gadolinium complexes and the energy match between the ligand and the central rare earth ions was studied. The photophysical properties such as luminescence properties and intramolecular energy transfer match between rare earth ions and ligands and between ligands were discussed. The result indicates that terbium complexes with N Phenylanthranilic acid and 1,10 Phenanthroline have excellent luminescence properties.
