  Luminescence enhancement of the Tb(III) ion with the thenoyltrifluoroacetonate ligand acting as an efficient sensitizer

  摘要：

  The synthesis, structural investigation, and photophysical properties of the complex [Tb(TTA)(2)(NO3) (TPPO)(2)] are reported. Unlike the analog tris-diketonate complex [Tb(TTA)(3)(TPPO)(2)], the new complex presents abnormally high luminescence intensity centered on the terbium ion. Our results clearly suggest a higher energy transfer efficiency from the TEA antenna ligand to the Tb(III) ion in the bis-diketonate complex compared with that in the tris-diketonate complex. A mechanism involving the increasing of triplet state energy when one TTA ligand is replaced by the NO3- group in the first coordination sphere is suggested and experimentally investigated to explain the anomalous luminescence properties of the new complex [Tb(TTA)(2)(NO3)(TPPO)(2)].

  We report here the fast synthesis by microwave assisted technique of four ternary Ln(TTA)(3)(TPPO)(2) complexes, where Ln = La(III), Eu(III), Tb(III) and Tm(III), TTA = 2-thenoyltrifluoroacetone, and TPPO = triphenylphosphine oxide, which are of interest in luminescence applications. Using this method, the reaction time was decreased to one minute with minimal purification step and the yields are comparable Kto literature values. The target complexes were characterized using H-1,C-13, F-19, P-31 NMR and FTIR spectroscopy, MALDI-TOF mass spectrometry and single -crystal X-ray diffraction. Further, we discuss here a hitherto unreported extensive network of hydrogen bonding interactions present in these complexes. (C) 2017 Elsevier B.V. All rights reserved.
