Abstract Research over the years has revealed immense potential of metal–organic frameworks (MOFs) for purifying olefins such as ethylene (C 2 H 4 ) and propylene 3 6 ). However, many these MOFs face challenges in terms economic viability, particularly production scalability, long‐term stability, process capability. In this study, we present a low‐cost easily scalable synthesis robust MOF material (JNU‐74a), featuring balanced surface polarity that allows one‐step C purification from methanol‐to‐olefin (MTO) products. By incorporating highly electronegative atoms on nonpolar surface, JNU‐74a exhibits substantially larger absorption capacity stronger binding affinity ethane compared to , evidenced by their gas adsorption isotherms heats measurements. In‐depth analyses through situ single‐crystal X‐ray diffraction (SCXRD) gas@JNU‐74a unveil multiple supramolecular bindings favor confirming preferential . Breakthrough experiments demonstrate can efficiently produce polymer‐grade (≥99.95%) (≥99.5%) /C mixtures different ratios single adsorption‐desorption cycle. With its impressive separation capability, high chemical cost‐effective production, holds promise olefin MTO products other challenging industrial separations.
