Synthesis and structural studies of a lanthanide complex of a calix[4]arene tris-amide

摘要

The coordination chemistry of amide-substituted calixarenes is reviewed.The synthesis of a gadolinium complex of a tris-amide calix[4]arene is described,involving the reaction of 5,11,17,23-tetra-tert-butyl-24-hydroxy-26,27,28-tris(diethylcarba-moylmethoxy)calix[4]arene (L) with gadolinium picrate dodecahydrate.Structural studies demonstrated that the complex can be formulated as [(pic-O)Gd{(L-H)(EtOH)}](pic)-2 EtOH.
