A facile synthesis of decatosylate pillar[5]arene 1 is reported in excellent yield (>70%). The high yield is attributed to a self-template effect of the pendant tosylate arms. The X-ray crystal structure shows the formation of a linear supramolecular polymer, stabilised by intermolecular pillar[5]arene-tosylate inclusion complexes. These polymeric arrays persist in solution and form rod-like microfibril nanostructures evidenced by SEM.
据报道，一种简便的方法可高收率（>70%）合成癸基对甲苯磺酸酯柱[5]芳烃1。高收率归因于侧链对甲苯磺酸酯臂的自模板效应。X射线晶体结构表明形成了线性超分子聚合物，该聚合物通过分子间柱[5]芳烃 - 对甲苯磺酸酯包合物得以稳定。这些聚合物阵列在溶液中持续存在，并形成棒状微纤维纳米结构，扫描电子显微镜证明了这一点。
