Abstract
The present project aims the synthesis of the complexes [Ln1(hfa)3(tppo)-(¼-L)-Ln2(hfa)3(tppo)], which Ln1 = Tb(III) and Ln2 = Eu(III); hfa = 1,1,1,5,5,5-hexafluoropentane-2,4-dione; tppo = triphenylphosphine oxide; and the bridge ligand L = [(diphenylphosphoryl)R](diphenyl)phosphine oxide (R = methyl, ethyl, propyl or butyl). It will be evaluated the efficiency of the energy transfer/ret…
