Rational preparation of an adaptive cavity-like enzyme is a great challenge for chemists. Herein, a new self-assembly strategy for the rational preparation of metal–organic tubes with nano-channels has been developed; both 1D metal–organic tube and corresponding 2D layered assemblies can be selectively synthesized driven by different templates; reversible sheet-to-tube transformation can be realized and the key intermediate has been identified. Furthermore, the newly formed nano-channel displays excellent polarity-selectivity for encapsulation of guest molecules, and can be further expanded or contracted through guest-driven adaptive deformation; even induced by very similar guest molecules, the adaptive deformations can also be obviously distinguished. Finally, the key chemicals benzene/hexane with a similar size can also be effectively separated by such nano-channels in the liquid phase. Our work not only provides a new synthetic strategy for the rational synthesis of metal–organic tubes with a reversible sheet-to-tube transformation character, but also gives a potential method for the construction of adaptive host-like enzymes and an in-depth understanding of the nature of adaptive host and guest molecules.

金属有机管或层状组件：可逆片到管的转换和自适应识别
合理制备适应性空腔样酶对化学家来说是一个巨大的挑战。在此，开发了一种新的自组装策略，用于合理制备具有纳米通道的金属有机管；一维金属有机管和相应的二维层状组件都可以通过不同的模板驱动选择性合成；可以实现可逆的片材到管材的转变，并且已经确定了关键中间体。此外，新形成的纳米通道对客体分子的封装表现出优异的极性选择性，并且可以通过客体驱动的自适应变形进一步扩展或收缩；即使是由非常相似的客体分子引起的，自适应变形也可以明显地区分。最后，具有相似尺寸的关键化学品苯/己烷也可以通过这种纳米通道在液相中有效分离。我们的工作不仅为合理合成具有可逆片到管转化特性的金属有机管提供了一种新的合成策略，而且为构建适应性宿主类酶提供了一种潜在的方法，并为该酶的深入理解提供了可能。适应性宿主和客体分子的性质。
