Europium(III) complexes of [Eu(beta-diketone)4]- and [Eu(beta-diketone)3(phen)] were synthesized and their photophysical properties were investigated. The beta-diketones used in this work were 4,4,4-trifluoro-1-(2-furyl)-1,3-butanedione, 4,4,4-Trifluoro-1-(2-naphthyl)-1,3-butanedione, 1-(2-Thenoyl)-3,3,3-trifluoroacetone, 4,4,4-Trifluoro-1-phenyl-1,3-butanedione and dibenzoylmethane. 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 emission proved that the energy transfer took place effectively via the beta-diketone ligand, no matter whether phen was included or not in the complex. In this presentation, the energy transfer between the beta-diketone ligands and the europium(III) ion will be precisely discussed.
