Synthesis, Characterization and Luminescence of a Series Europium Complexes with 1 Phenyl 3 Methyl 4 Acyl 5 Pyrazolones

A series of europium complexes with 4 acyl substituted pyrazolones: Eu(L) 3.2H 2O, where L=1 phenyl 3 methyl 4 acetyl 5 pyrazolone (PMAP); 1 phenyl 3 methyl 4 propionyl 5 pyrazolone(PMPP); 1 phenyl 3 methyl 4 isobutyryl 5 pyrazolone (PMIBP); 1 phenyl 3 methyl 4 pivaloyl 5 pyrazolone (PMPV P) and 1 phenyl 3 methyl 4 benzoyl 5 pyrazolone (PMBP), were synthesized and identified by elemental analysis. The complexes were characterized by FT IR, UV vis spectra, TG DTA analysis and X ray diffraction. The luminescences of the solid powder complexes were also studied. Results show that the fluorescence intensities of these complexes strongly depend on the different substituted 4 acyl groups.
