  Claisen condensation of diacetylated fused aromatic and heteroaromatic compounds (fluorene, dibenzofuran, dibenzothiophene, or carbazole) with polyfluorocarboxylic acids esters in the presence of bases has afforded the ligands containing two -diketonate groups. Their complexation with Eu3+ ions has been studied by the luminescence spectral method.
