Synthesis and luminescent properties of Eu3+, Gd3+, and Tb3+ complex compounds with some N-substituted phthalamic acids

Abstract

A number of europium(III), terbium(III), and gadolinium(III) coordinationcompounds with N-substituted phthalamic acidswere synthesized. Composition and structure of the ligands and the obtainedcomplex compounds were confirmed by NMR and IR spectroscopy andthermogravimetric analysis. It was found that terbium(III) and europium(III)coordination compounds with N-phenylphthalamic acid possess the most pronouncedluminescence
