Seven new tris(β-diketonate)ytterbium(III) complexes with the general formula [Yb(β-diketonate)3(5NO2phen)] [the β-diketone is 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione (1), 4,4,4-trifluoro-1-(2-furyl)-1,3-butanedione (2), 1,1,1-trifluoro-2,4-pentanedione (3), 1,1,1-trifluoro-5,5-dimethyl-2,4-hexanedione (4), 1,1,1,5,5,6,6,7,7,7-decafluoro-2,4-heptanedione (5), 2,4-hexanedione (6) or 2,6-dimethyl-3,5-heptanedione (7), and 5NO2phen = 5-nitro-1,10-phenanthroline] were synthesized and characterized by elemental anal., attenuated total reflectance-FTIR and photoluminescence spectroscopy. Single crystal x-ray structures have been determined for three fluorinated complexes (3-5) and ground state geometries of the other four complexes have been predicted using the Sparkle/PM6 model (1-2, 6-7). These exptl. and semi-empirical structures reveal octacoordination around the Yb3+ ion. Photoluminescence studies and lifetime measurements show that the increase in the fluorinated β-diketonate chain length is associated with a decrease in Yb3+ luminescence intensity of the 2F5/2 → 2F7/2 transition at ∼980 nm and the 2F5/2 excited state lifetime, while the ligand lifetime value remains almost unaffected. Finally, fluorination of the ligands is only advised when the complexes are to be used for co-doping with isostructural Er3+ complexes for optical amplifiers, since it leads to a slight decrease in luminescence intensity for the same β-diketonate chain length.
After consulting a lot of data, we found that this compound(18362-64-6)Computed Properties of C9H16O2 can be used in many types of reactions. And in most cases, this compound has more advantages.
