The separation of acetylene (C2H2), ethylene (C2H4), and carbon dioxide (CO2) is critical in the chemical industry, driven by increasing demand for high-purity C2H2 C2H4. While metal-organic frameworks (MOFs) offer an energy-efficient approach adsorptive gas separation, achieving sub-angstrom precision pore size adjustment remains challenging. In this work, we leverage two synergistic mechanisms a double-interpenetrated framework: (1) global structural flexibility, arising from dynamic displacement subnetworks to tailor dimensions, (2) local enabled counterion ligand rotation, modulate aperture binding affinity precise molecular discrimination. A series isostructural MOFs, NUS-33-CF3SO3 NUS-34-BF4, were designed enable one-step purification C2H4 concurrent recovery ternary mixtures. Within pores optimal interplay between counterion-mediated host-guest interactions framework adaptability enables simultaneous regulation static kinetic adsorption properties. Notably, NUS-34-BF4 achieves productivity 2.62 mmol/g uptake 1.26 mmol/g. This study highlights pivotal yet underexplored role counterions as gatekeepers, offering tunable strategy engineer environments flexible MOFs advanced separations.

Similar to conventional solids, porous materials have demonstrated rigid and flexible behaviors. Here, we show that pores can be not just elastic but also plastic. By variation of the hydrogen-bonding ability steric hindrance ligand side groups, energy difference barrier between metastable states a framework are fine-tuned enable plastic behavior. All pore structures transform target ones in atmospheres guests with sufficiently high pressures, all shaped remain unchanged after guest removal, resulting optimized host-guest recognitions for guests. Up 6-fold increase adsorption selectivity 9-fold purification productivity CO2 capture coalmine CH4 upgrading, even inversion CO2/C2H2 selectivity, been achieved by reversible pore-shaping single plastic-pore adsorbent. The realization creates an opportunity on-demand switching separation functions performances.

Covalent organic frameworks (COFs), characterized by high surface areas and tunable pore structures/environments, are regarded as a promising alternative to physisorption H2 storage materials. However, their interaction with hydrogen is often too weak, necessitating the exploration of strategies enhance sorption heat. Herein, we strengthened adsorption induction COF on through polarized wall engineering. The fluorine groups three-dimensional COFs polarize surrounding regions, resulting in heat sites. Due enhanced heat, total uptake 3D-F-COF up 5.96 wt % at 77 K 90 bar. Moreover, enhancement effect polar group does not involve chemisorption, material exhibits excellent cycling stability. These results reveal that modulating incorporating strategy for achieving efficient porous
