Stability of Divalent Europium in an Ionic Liquid: Spectroscopic Investigations in 1-Methyl-3-butylimidazolium Hexafluorophosphate
Résumé
In this work, devoted to 1-methyl-3-butylimidazolium hexafluorophosphate ionic liquid (BumimPF 6), the importance of the purity of the solvent for spectroscopic investigations is highlighted. Results from small angle X-ray scattering indicate that the pure solvent exhibits a local organization. Europium(II), which appears to be unusually stable in BumimPF 6 , is characterized by spectroscopic techniques (absorption, luminescence). Solvation of Eu(II) in BumimPF 6 and complexation effects in the presence of the crown ether 15C5 solubilized in the ionic liquid are discussed.
