Efficiently obtaining both high-purity gas-phase and adsorbed-phase products in a single physisorption process presents the challenge of simultaneously achieving high selectivity uptake rapid diffusion adsorbents. With focus on natural gas purification acetylene production, we report for first time that synergistic ligand/anion binding mode multiple pathways robust 2D layered ultramicroporous framework (ZUL-100) enable unprecedented carbon dioxide/methane acetylene/methane separation performance. Taking advantage its rich anion, functional ligand ,and rigid 3D interpenetrated channels, ZUL-100 achieved record IAST selectivities equimolar (3.2 × 10
