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

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.
