[2]Pseudorotaxanes, [2]rotaxanes and metal–organic rotaxane framework materials that utilise DB24C8 as the wheel component are well known and structural variations based on changing the axle component are common. Studies in which the DB24C8 wheel is structurally modified are much more limited. Herein, is described the synthesis of symmetrical DB24C8 analogues containing four CH2OR (R = CH2CH2CH3, CH2(C6H5)
[2]假轮烷,[2]轮烷和使用DB24C8作为车轮组件的金属有机轮烷骨架材料是众所周知的,并且基于改变车轴组件的结构变化是常见的。对DB24C8砂轮进行结构改造的研究非常有限。本文描述了对称的DB24C8类似物的合成,该对称DB24C8类似物包含四个CH 2 OR(R = CH 2 CH 2 CH 3,CH 2(C 6 H 5),C 6 H 5和C 6 H 4(4-COOEt))在芳香环的4和5位上的取代基。描述了这些分子附件对衍生自这些新车轮的互穿互锁分子的稳定性和结构的影响。相对于DB24C8,主要影响是[2]假轮烷的形成的缔合常数增加,[2]轮烷的晶体堆积和2D MORF的内部结构变化(R = C 6 H 5)。DB24C8。
