of foldamer‐type hosts, various kinds of recognition arrays are expected to be developed. Here, a pyridine‐acetylene‐aniline unit is presented as a new class of a saccharide recognition array. The conformational stabilities of this array were analyzed by DFT calculation, and suggested that a pyridine‐acetylene‐aniline oligomer tends to form a helical structure. An oligomer of this array was synthesized
为了创建折叠式主机的新功能,预计将开发各种识别阵列。在这里,
吡啶-

苯胺单元被作为一种新型的
糖类识别阵列。通过DFT计算分析了该阵列的构象稳定性,表明

苯胺低聚物趋于形成螺旋结构。合成了该阵列的低聚物,并通过1 H NMR测量证实了其与辛基β -
D-吡喃葡萄糖苷的缔合。UV / Vis,圆二色性和荧光滴定实验表明,它对非极性溶剂中的辛基糖苷具有很高的亲和力(K a = 10 4至10 5 M -1)。该低聚物在碱性条件下相对稳定,因此预期该阵列可用于糖的衍生化。一种由4-(二烷基
