Synthesis and Luminescent Properties of Eu3+, Gd3+, and Tb3+ Complex Compounds with Some N-Substituted Phthalamic Acids

摘要

A number of europium(III), terbium(III), and gadolinium(III) coordination compounds with N-substituted phthalamic acids were synthesized. Composition and structure of the ligands and the obtained complex compounds were confirmed by NMR and IR spectroscopy and thermogravimetric analysis. It was found that terbium(III) and europium(III) coordination compounds with N-phenylphthalamic acid possess the most pronounced luminescence.
