论文摘要
通过动态和VT NMR研究了一系列[2]旋转烷的多站点氢键汉密尔顿型受体的大环的固有运动。在这些旋转植物中，分子轴上氢键基序的变化性质和数量影响了环动力学。在两个站点变体中观察到了与存在的汉密尔顿大环中存在的氢键与存在的汉密尔顿大环中存在的氢键选择性相互作用的，并在25°C的快速穿梭（在25°C下为72 kHz）选择性相互作用。
Inherent movement of a macrocycle comprising a multi-site hydrogen bonding Hamilton-type receptor in a series of [2]rotaxanes was investigated by dynamic and VT NMR. In these rotaxanes the varying nature and number of hydrogen-bond motifs and stations on the molecular axles influenced ring dynamics. Triazole stations interact selectively by hydrogen bonding with the isophthalamide amide bonds present in the Hamilton macrocycle and fast shuttling (72 kHz at 25 °C) was observed in a two station variant.
