as the dynamic equilibrium between imine‐bridged rotaxane 5 and [2]rotaxane 7 by using various combinations of axles (1 A,B), macrocycles (2 a–e), and side‐stations (XYL and TEG). In the threading process, the flexibility of the macrocycle and the substituent groups at the para position of the aniline moieties affect the preparation of the threaded imines. The size of the imine‐bridging station and the
亚胺桥接的轮烷是一种新型的轮烷,其中轴和大环通过亚胺键连接。我们以前曾报道过,在亚胺桥接的轮烷中5,大环的穿梭运动可以通过改变温度来控制。在这项研究中,我们调查车轴和大环化合物的结构如何影响亚胺桥接轮烷的结构之间以及亚胺桥接轮烷动态平衡5和[2]轮烷7通过使用车轴的各种组合(1分甲,乙),大环(2 a – e)和边站(XYL和TEG)。在穿线过程中,大环的柔性和苯胺部分对位的取代基会影响带线亚胺的制备。亚胺桥键和大环系链的大小会影响酸性条件下亚胺键的水解。
