The efficient separation of acetylene (CH) and ethylene (CH) is an important and complex process in the industry. Herein, we report a new family of -topologic coordination frameworks (termed to ) with CuMF (M = Si, Ti, and Zr) nodes. These charged frameworks are compensated by different counterbalanced ions (MF, BF, and Cl), yielding changes in the size of the window apertures. Among these frameworks, (activated ) shows good adsorption selectivity of CH/CH and also significant ability in recovering both highly pure CH (99.95%) and CH (99.98%). Our work not only presents a potential alternative for energy-saving purification of C2 hydrocarbons but also provides a new approach for tuning the function of charged porous materials.
乙炔（CH）和乙烯（CH）的高效分离是工业中一个重要且复杂的过程。在此，我们报道了一类新的具有CuMF（M = Si、Ti和Zr）节点的拓扑配位框架（称为 到 ）。这些带电框架由不同的抗衡离子（MF、BF和Cl）补偿，导致窗口孔径大小发生变化。在这些框架中，（活化的 ）对CH/CH表现出良好的吸附选择性，并且在回收高纯度CH（99.95%）和CH（99.98%）方面也具有显著能力。我们的工作不仅为C2烃的节能纯化提供了一种潜在的替代方案，还为调节带电多孔材料的功能提供了一种新方法。
