通过有机分子的自组装产生的超分子纳米管可以具有独特的结构特征，例如没有分支的一维形态，可区分的内表面和外表面以及膜壁，或者中空且具有高纵横比的结构。将响应外部化学或物理刺激的官能团并入超分子纳米管的组成有机分子中，使我们能够通过施加这种刺激来彻底改变纳米管的结构。这种能力为客体化合物的封装、储存和释放提供了一系列可控的方法，这有望在物理、化学、生物和医学领域中有用。在这篇文章中，我回顾了我们小组开发的超分子纳米管，其表现出响应于pH值，化学反应，光，温度或湿度的形态转变。
Supramolecular nanotubes produced by self‐assembly of organic molecules can have unique structural features such as a one‐dimensional morphology with no branching, distinguishable inner and outer surfaces and membrane walls, or a structure that is hollow and has a high aspect ratio. Incorporation of functional groups that respond to external chemical or physical stimuli into the constituent organic molecules of supramolecular nanotubes allows us to drastically change the structure of the nanotubes by applying such stimuli. This ability affords an array of controllable approaches for the encapsulation, storage, and release of guest compounds, which is expected to be useful in the fields of physics, chemistry, biology, and medicine. In this article, I review the supramolecular nanotubes developed by our group that exhibit morphological transformations in response to pH, chemical reaction, light, temperature, or moisture.
