Outside Front Cover: Highly Selective Adsorption of Para‐Xylene, Ethylbenzene, and Explicit Exclusion of Ortho‐Xylene from Xylene Isomers Using a Pillar‐Layered MOF with Tuned Pore Channels

Molecular sieving of xylene isomers was achieved by Myoung Soo Lah et al. in their Research Article (e202512244), using a pillar-layered MOF, Ni-HDB, incorporating DABCO pillars that block lateral diffusion and enforce transport through elliptical windows. This confined geometry enables record selectivity for PX and EB over OX via kinetic sieving, offering a new strategy for energy-efficient hydrocarbon separation.
