The development of porous solids for adsorptive separation propylene and propane remains an important challenging line research. State-of-the-art sorbent materials often suffer from the trade-off between adsorption capacity selectivity. Here, we report regulated in a metal-organic framework via designed pore distortion. distorted structure HIAM-301 successfully excludes thus achieved simultaneously high selectivity (>150) large (∼3.2 mmol/g) at 298 K 1 bar. Dynamic breakthrough measurements validated excellent propylene. In situ neutron powder diffraction inelastic scattering revealed binding domains adsorbed molecules as well host-guest interaction dynamics. This study presents new benchmark propane.
