Four metal–organic frameworks employing the m-terphenyl diisophthalate linker molecule with 2′ substitution by P(v)-based functional groups of the central aryl have been synthesised.

Modeling adsorption properties of structurally deformed metal-organic frameworks using structure-property map

Structural deformation and collapse in metal-organic frameworks (MOFs) can lead to loss of long-range order, making it a challenge to model these amorphous materials using conventional computational methods. In this work, we show that a structure-property map consisting of simulated data for crystalline MOFs can be used to indirectly obtain adsorption properties of structurally deformed MOFs. The structure-property map (with dimensions such as Henry coefficient, heat of adsorption, and pore volume) was constructed using a large data set of over 12000 crystalline MOFs from molecular simulations. By mapping the experimental data points of deformed SNU-200, MOF-5, and Ni-MOF-74 onto this structure-property map, we show that the experimentally deformed MOFs share similar adsorption properties with their nearest neighbor crystalline structures. Once the nearest neighbor crystalline MOFs for a deformed MOF are selected from a structure-property map at a specific condition, then the adsorption properties of these MOFs can be successfully transformed onto the degraded MOFs, leading to a new way to obtain properties of materials whose structural information is lost.

Ambient pressure synthesis of MIL-100(Fe) MOF from homogeneous solution using a redox pathway

At normal pressure a DMSO–nitrate redox pathway, which is amenable to up-scaling or continuous flow reaction, gave MIL-100(Fe) with surface areas of S_BET = 1791 m² g⁻¹ and pore volumes of V_pore = 0.82 cm³ g⁻¹.

Synthesis, characterization and magnetism of metal–organic compounds: role of the positions of the coordinating groups of a meso-flexible ligand in placing anisotropy to exhibit spin-canting behaviour

Magnetic anisotropy can be included in metal–organic coordination polymers by altering the position of the coordinating groups on the skeleton of the ligand.

1D chains, 2D networks and 3D interdigitated frameworks of isoorotic acid or 4,4′-bipyridyl and isoorotic acid: syntheses, structures, and sorption properties
