Abstract

The rational design of metal–organic framework adsorbents is crucial for target gas separation. Herein, we report two three-dimensional MOFs with different topologies by regulating metal ions with amino-functionalized V-type ligands. Adsorption isotherms and Grand Canonical Monte Carlo simulation reveal that UPC-122 with channel-cavity structure has the potential to separate C₂H₂/C₂H₄ at room temperature with a separation ratio of 2.35 (50/50).
