TL;DR: Control over pore chemistry and size in metal coordination networks with hexafluorosilicate and organic linkers for the purpose of preferential binding and orderly assembly of acetylene molecules through cooperative host-guest and/or guest-guer interactions is reported.

TL;DR: In this article, a number of different separation strategies can be employed to achieve the desired desired separation performance using microporous metal-organic frameworks (MOFs), including selective binding with the metal atoms of the framework, exploiting differences in molecular packing efficiencies within the ordered pore structures, utilizing selectivities based on the framework flexibility and gate-opening mechanisms, and molecular sieving.

TL;DR: The adsorption kinetic measurements suggest that the diffusivities of CO(2) and CH(4) on Mg-MOF-74 were comparable to those on zeolite 13X and the pressure-dependent equilibrium selectivity of CO (2) over CH (4) (q(CO2)/q(CH4)) in the M g-MOf-74 adsorbent showed a trend similar to that of zeolites 13X.

TL;DR: The relatively high values of adsorption selectivity suggest that it is feasible to separate ethylene/ethane, propylene/propane, and propylene-ethylene pairs in a vacuum swing adsorptive process using Mg-MOF-74 as an adsorbent.

TL;DR: An ideal porous material, SIFSIX-14-Cu-i (also termed as UTSA-200), is reported with ultrafine tuning of pore size to effectively block ethylene molecules but to take up a record-high amount of acetylene, which sets up new benchmarks for both the adsorption capacity and selectivity.
