Picking up the thread: The macrocycle bis‐p‐xylyl[26]crown‐6 is capable of forming pseudorotaxane‐like structures with single, nonconjugated urea or amide moieties when assisted by templating Na+ ions (see example). By using this approach, rotaxanes were synthesized with glycine residues or the repeating unit of nylon‐6,6 as key components in the threadlike units.
接好线:在模板化Na +离子的辅助下,大环双对二甲苯基[26] crown-6能够与单个,非共轭尿素或酰胺部分形成类拟轮烷状结构(请参见示例)。通过这种方法,合成了轮状烷,其中甘氨酸残基或尼龙-6,6的重复单元是线状单元中的关键成分。
