Abstract Constructing a metal‐free adsorbent for one‐step separation of C 2 H 4 from mixture gas C2, is great significance and challenging. Here, porous aromatic cage ( PAC‐1 ) based on aldehyde‐amine condensation reported with diamond‐like interconnected cavity‐channel pores purification ethylene. exhibits superior (52.6 cm 3 g −1 6 (46.7 uptakes as well impressive /C selectivity (1.5) (1.4), remaining at the forefront advanced ‐selective adsorbents non‐metallic materials. The adsorption enthalpy (Q st 23.6 kJ mol , which requires less energy to regenerate than conventional MOF Breakthrough experiments demonstrate that can reduce penetration rate or through adsorbent, present quite valuable gas. Molecular simulations DFT studies have shown oxygen sites C─H in channels are more favorable anchor interaction over by 1.48 kcal C─H…π point cavity preferred 1.16 turn results .
