This tutorial review summarizes the progress made towards mechanically interlocked daisy chains. Such materials can be seen as a further development in polymer science, where the conventional covalent interlinking bonds are replaced by supramolecular binding concepts. Materials in which the mechanical bond is an integral part of the polymeric backbone are expected to possess unique macroscopic properties and are therefore the synthetic aim in an ever growing research community. After introducing general considerations about daisy chains, the most common analytic methods to get insight into the aggregation behaviour of such self-complementary monomers are presented. Cyclodextrins/aromatic rods, crown ethers/cationic rods and pillararenes/alkyl chains are systems used to achieve daisy chain-like molecular arrays. By comparison of the reported systems, conclusions about an improved structural design are drawn.
本教程综述总结了在机械互锁轮烷方面取得的进展。这类材料可以被视为高分子科学的进一步发展，其中传统的共价交联键被超分子结合概念所取代。预期将机械键作为聚合物主链的一个组成部分的材料将具有独特的宏观性质，因此是日益增长的研究群体中的合成目标。在介绍了有关轮烷的一般考虑因素之后，提出了最常见的分析方法来深入了解此类自互补单体的聚集行为。使用环糊精/芳香族棒、冠醚/阳离子棒和柱芳烃/烷基链来实现类似轮烷的分子排列。通过对报道的系统进行比较，得出了关于改进结构设计的结论。
