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.

Developing high-performance adsorbents for iodine uptake and storage has become an urgent priority safe disposal long-term of nuclear waste. In this work, two cyclic lanthanide-aluminum clusters with the formula [Ln12Al72(hmp)60(C2H5O2)6(μ2-OH)120(μ3-OH)18(H2O)30]Cl24·(NO3)24·(H2O)x (Ln = Tb, x ≈ 80, Tb12Al72; Ln Gd, 100, Gd12Al72; Hhmp 2-(hydroxymethyl)pyridine C2H6O2 ethylene glycol) are reported. Single-crystal analysis reveals that its inner diameter is approximately 1.1 nm, outer 4.1 nm a thickness 3.1 nm. The packing through intermolecular interactions generates 3D supramolecular structure one-dimensional channels. Investigation adsorption performance cluster indicates capacity 3.14 g g-1 Tb12Al72 Gd12Al72. effectiveness largely due to accessible micropore along high density pyridine rings abundant hydroxyl oxygen atoms. Consistently, DFT calculations indicate [Al(μ-OH)n] ring regions synergistically facilitate adsorption, effectively promoting dissociation I2 into I- anions. This unique environment enhances electrostatic stabilization polyiodide anions strong Coulombic attraction, significantly boosting capture iodine.
