【摘要】 通过扩散法,采用氨基对丙烯酸甲酯的M ichael加成反应和酯基的酰胺化反应交替进行,合成了4种树枝型对叔丁基杯[n]芳烃酰胺衍生物(n=6,8)。利用紫外-可见光谱(UV-V is)研究了它们对不同金属离子的识别作用。结果表明,这4种主体对Ag+、UO22+具有最好的选择性识别性能,主客体间分别形成了1∶2或1∶3的络合物。更多还原

【Abstract】 Dendritic p-t-butylcalix\arene amide derivatives with terminal amino groups of the first and（second） generations were synthesized from the ammonolysis of ethyl calixylacetate with 1,6-diaminohexane and Michael addition of methyl acrylate.Their structures were confirmed by IR,¹H NMR.The recognition properties of these amide derivatives for several kinds of metal ions were studied with UV-Vis spectroscopy.In the processes of recognition they showed a great affinity for soft Ag⁺ and UO²⁺₂ ions and formed 1∶[KG-*3/5]2 or 1∶[KG-*3/5]3（stoichiometric） complexes.更多还原
