  Tailoring the Adsorption and Reaction Chemistry of the Metal–Organic Frameworks UiO, UiONH 2, and HKUST-1 via the Incorporation of Molecular Guests Ann M. Ploskonka and Jared B. DeCoste ACS Applied Materials & Interfaces 9 (25),   The structures of four iron(III) carboxylate materials with the MIL structure and the guest molecules water, pyridine, or 2,6-dimethylpyridine (2,6-lutidine) have been solved and refined from high-resolution powder X-ray diffraction data. These materials have porous structures constructed from infinite chains of trans-corner-shared {FeO4(OH,F)2} octahedra cross-linked by benzene

For example, gas permeabilities of TBDAFDA-PI were Barrer for H 2 and Barrer for CO 2, while the corresponding selectivities were for H 2 /CH 4, for H 2 /N 2 and for CO 2 /CH 4, which were close to or beyond upper :// The chemical moieties within the framework can be spatially controlled using this bottom‐up synthesis approach. 1 These frameworks stand out through their surprisingly high porosity 2 and fascinating versatility. 3 MOFs, or more broadly, coordination polymers, have been known since the late s 4 and early s, 5 although it was not until
