malononitrile and benzaldehyde was performed to construct the stoppers and connected the pseudorotaxanes with stoppers to generate 1–4. The structures of [3]rotaxanes and their self-assembly behaviors were characterized by 1H NMR, 13C NMR, NOESY, HR-ESI-MS, DLS and TEM technologies. We hope that pillar[5]arene based [3]rotaxanes may have potential applications in drug delivery systems and molecular devices.
摘要成功合成了四个基于[5]
芳烃的柱基[3]轮
烷烃(1-4),它们涉及两个1,4-二乙氧基立柱[5]
芳烃(
DEP5)环和一个哑铃状组分。哑铃形分子包含一个更长的桥,两个三唑位点和两个多组分塞子。将带有两个
苯甲醛单元的线性客体(G1-G4)穿入
DEP5环后,进行
二甲酮,
丙二腈和
苯甲醛的碱催化三组分反应,以构建塞子,并将拟轮烷与塞子连接以生成1-4。[1] NMR,13 C NMR,NOESY,HR-ESI-MS,DLS和
TEM技术表征了[3]轮烷的结构及其自组装行为。我们希望基于柱[5]
芳烃的[3]轮烷可能在药物递送系统和分子装置中具有潜在的应用。
