Enabling High C2H2 Storage and Efficient C2H2/CO2 Separation in a Cage-like MOF with Multiple Supramolecular Binding Sites

Separating acetylene (C2H2) from carbon dioxide (CO2) is of great industrial importance for achieving high-purity C2H2 (>99%). However, overcoming the trade-off effect between adsorption capacity and selectivity remains a daunting...
