在这篇通讯中，我们构建了一个包含苯并-21-冠-7、二苯并-24-冠-8和两个仲铵盐的竞争自分类系统，然后对其进行修饰，得到具有特定轮子序列的杂环[3]拟轮烷。利用这两个系统，我们成功地演示了综合自排序的概念及其之间的关系。此外，基于这种自分类方案，我们还合成了一种具有高效阻挡级联的杂环[3]轮烷。
In this Communication, a competing self-sorting system containing benzo-21-crown-7, dibenzo-24-crown-8 and two secondary ammonium salts is constructed, which is then modified to achieve a hetero[3]pseudorotaxane with a specific sequence of wheels. With these two systems, we successfully demonstrate the concept of integrative self-sorting, and their relation. Futhermore, based on this self-sorting scheme, a hetero[3]rotaxane with an efficient stopper cascade has been synthesized.
