  用于提取镧系离子的氟化 β-二酮：其 EuIII 配合物的光物理性质和水合数

  摘要：

  合成了具有一系列衍生自 3,5-庚二酮的可变氟化配体的三（β-二酮）铕（III），目的是确定它们在萃取条件下的水合状态。通过测量水和氘化水中 Eu(5D0) 激发能级的寿命来确定配位水分子的数量。在用 0.1 M NaClO4 水溶液摇动氯仿溶液 10 分钟后，水合增益 (Δq = q – q0) 取决于二酮的氟化程度：一个甲基的氟化导致大约 Δq 的减少。0.5 个单位，而一个乙基的氟化导致约 0.5 个单位的减少。1.3个单位。高度氟化的配合物（即具有六氟乙酰丙酮化物和相关配体）显示出接近 1 的水合数，而低氟化化合物（或非氟化化合物，如乙酰丙酮络合物）具有接近于两个的水合状态。还描述了 EuIII β-二酮的光物理特性，并重新研究和详细讨论了氟化 β-二酮的合成。
