Europium(III) complexes with homoleptic Schiff-base, o-N2O4, and mixed o-N2O4 and phen ( phen = 1,10-phenanthroline ) were synthesized and their photophysical properties were investigated. The schiff base, o-N2O4H2 ( o-N2O4H2 = 2,2'-(1E,1'E)-(1,2-phenylenebis(azan-1-yl-1-ylidene))bis(methan-1-yl-1-ylidene)dibenzoic acid ) , used in this work as chelating ligand was synthesised using 2-carboxybenzaldehyde and o-phenylenediamine. The synthesized Eu(III) complexes were confirmed with EA, ICP and TGA. The Eu(III) complexes excited at UV produced sensitized red-luminescence. The excitation spectra measured by monitoring the red emission proved that the energy transfer took place effectively via the o-N2O4 ligand, no matter whether phen was included or not in the complex. In this presentation, the energy transfer between the o-N2O4 and the europium(III) ion will be precisely discussed.
