Synthesis and Characterization of Complexes of Calix［8］ Arene Ketone Derivative with Praseodymium or Europium

摘要:

以氯丙酮作为亲电试剂与对叔丁基杯［8］芳烃发生亲电取代反应制得杯［8］酮衍生物,并进一步合成了杯［8］酮衍生物与稀土镨、铕的固体配合物.通过元素分析、红外光谱、13C核磁共振、X射线衍射、热谱分析对产物进行了表征.结果表明,两种固体配合物均为单核型分子,每种固体配合物都以2个杯［8］酮衍生物配体中的氧原子和中心离子配位,其中每个酮衍生物配体各以3个氧原子参与配位.另外,在两种固体配合物中,3个N,N二甲基甲酰胺分子均以1个氮原子和中心离子配位.此时配位数为9,固体配合物呈对称的三冠三角棱柱结构.

Abstract:

Calix［8］arene ketone derivative was prepared by using electrophilic reagent chloroacetone and p-tert-butyl phenol through etectrophilic substitution reaction.And then the solid complexes of calix［8］arene ketone derivative with Praseodymium or Europium were further synthesized.Elemental analysis,infrared spectra,13CNMR,XRD and thermal spectra were used to characterize the products.The results show that two kinds of the solid complexes are mononuclear molecules,central rare earth metal ions are coordinated by six oxygen atoms from two calix［8］arene ketone derivative and three nitrogen atoms from three N,N-Dimethylformamide molecules,leading to formation of nine-coordinated solid complexes with symmetrical tricapped trigonal prism structure.
