A mechanical bond presents a combination of the best features of covalent and supramolecular chemistries (stability and structural integrity), plus a unique dynamic nature, that makes it a very interesting tool for materials chemistry. Here, we overview the chemistry of the mechanical bond applied to polymers, metal-organic frameworks (MOFs) and carbon nanotubes. We first describe synthetic strategies towards polycatenanes and polyrotaxanes, and highlight their potential impact in polymer chemistry, exemplified by their use to make stimuli-responsive gels and as binders in battery electrodes. We continue by showing how to include mechanically interlocked components in MOFs, and analyse the distinctive dynamic properties of the final constructs. Finally, we describe the strategies towards mechanically interlocked derivatives of single-walled carbon nanotubes (SWNTs), and discuss the potential of the mechanical bond to tackle some of the classic problems of SWNT chemistry.
机械键合结合了共价和超分子化学(稳定性和结构完整性)的最佳特性,加上独特的动态性质,使其成为材料化学非常有趣的工具。在这里,我们综述了机械键合在聚合物、金属有机骨架(MOFs)和碳纳米管中的应用化学。我们首先描述了制备聚轮烷和聚轮烷的合成策略,并强调了它们在聚合物化学中的潜在影响,例如它们用于制备刺激响应凝胶和电池电极中的粘合剂。接着,我们展示了如何在 MOFs 中包含机械互锁组件,并分析了最终结构的独特动态特性。最后,我们描述了制备单壁碳纳米管(SWNTs)机械互锁衍生物的策略,并讨论了机械键合解决 SWNT 化学经典问题的潜力。
