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.
在这项致力于研究1-甲基-3-丁基咪唑六氟磷酸盐离子液体（BumimPF₆）的工作中，强调了用于光谱研究的溶剂纯度的重要性。小角X射线散射结果表明，纯溶剂呈现出局部有序结构。在BumimPF₆中似乎异常稳定的铕（II），通过光谱技术（吸收、发光）进行了表征。讨论了铕（II）在BumimPF₆中的溶剂化作用以及在溶解于离子液体中的冠醚15C5存在下的络合效应。
