Separation of acetylene from carbon dioxide and ethylene is challenging in view of their similar sizes and physical properties. Metal-organic frameworks (MOFs) in general present themselves to be strong candidates for these separations owing to the presence of functional pore surfaces that can selectively capture a specific target molecule. Here, we report a novel 3D microporous cationic framework named JCM-1, which possesses imidazolium functional groups on the pore surfaces and pyrazolate as a metal binding group which is well known to form strong metal to ligand bond. The selective sorption of acetylene over carbon dioxide and ethylene in JCM-1 was successfully demonstrated by the equilibrium gas adsorption analysis as well as the dynamic breakthrough measurement. Furthermore, its excellent hydrolytic stability enabled the separation processes highly recyclable without a substantial loss in acetylene uptake capacity.
