Two calix[4]arene tetracarboxylates, [calix[4]arene tetraacetate (K(4)CTA) and calix[4]arene tetrabenzoate (K(4)CTB)] as their potassium salts, have been prepared. Employing these as precursors, two Ag(I) coordination polymers incorporating calix[4]arene units have been successfully prepared and their X-ray crystal structures have been determined. In these, the CTA and CTB derivatives are linearly bound to two and four silver atoms, respectively, to generate unusual tubular nanostructures. A comparative NMR study was undertaken to investigate the nature of the metal ion blocking of the tube as observed in the CTA-derived structure. The thermal properties for both coordination polymers were also examined.
已制备了两种杯[4]芳烃四羧酸酯，即[杯[4]芳烃四乙酸酯（K（4）CTA）和杯[4]芳烃四苯甲酸酯（K（4）CTB）]作为它们的钾盐。利用这些作为前体，成功制备了两种包含杯[4]芳烃单元的 Ag(I)配位聚合物，并确定了它们的 X 射线晶体结构。在这些结构中，CTA 和 CTB 衍生物分别与两个和四个银原子线性结合，生成了不寻常的管状纳米结构。进行了比较 NMR 研究以研究在 CTA 衍生结构中观察到的管中金属离子阻塞的性质。还检查了两种配位聚合物的热性能。
