Themed collection Metal-organic frameworks

Understanding the effect of functional sites on the MOF CO₂ adsorption capacity and selectivity.

Commercially available MOFs can be highly active, reusable catalysts for liquid-phase acid-catalyzed and aerobic oxidation reactions.

A discrete dinuclear Ag(I) tetrastilbazole undergoes a single-crystal-to-single-crystal reaction to form a 1D polycyclobutane.

A 2D coordination polymer has been shown to undergo a reversible solid-state to solid-state electrochemical conversion with retention of the network connectivity.

Here we report the successful growth of homogenous MOF thin films of HKUST-1 and ZIF-8 on mesoporous silica foam using a layer-by-layer method.

For a series of metal–organic frameworks with rht topology, we study computationally the effect of the linker length on the surface area, pore size, and pore volume, relating them with the hydrogen adsorption properties. The results provide new insights about the excess capacities and the pressures where the uptake maxima in the excess isotherms occur.

The stepwise deposition of a robust, MOF-5-analogue family as thin films is reported and the selective adsorption of probe molecules onto the films as a function of the linker functionalization is demonstrated.

Phase-pure metal–organic frameworks [Zn₄O(L)₃] are formed in one-pot reactions with liberation of accessible ‘metal-binding’ groups within the frameworks.

An imidazole-appended dipyrrin ligand yields, upon coordination to Cu(II) cations, a linear metallatecton that self-assembles with Cd(II) salts to afford grid-type MOFs which, upon parallel stacking, lead to porous crystals offering 1D channels.

A MOF PCN-124 exhibits selective adsorption of CO₂ over CH₄ and cooperative catalytic activity in a tandem deacetalization–Knoevenagel condensation reaction.

The successful synthesis, activation, and gas sorption properties of phase-pure IRMOF-8 is reported, solving a decade-old puzzle.

Thermal, water and mechanical resistant zirconium-based MOF materials with exceptionally high CH₄ and CO₂ adsorption uptakes.

A new Al-MOF denoted CAU-6 exhibits infinite column-shaped inorganic building units based on tridecanuclear Al-oxo-clusters and hydrophilic sorption behaviour.

The first functionalized 1,3,5-tris(4-carboxyphenyl)benzene (H₃BTB) ligands have been prepared that generate an isostructural, functionalized MOF-177 framework, as well as the novel, interpenetrated pcu-e framework.

Zr and Hf based MOFs with reo topology showing enhanced pore accessibility for large molecules and high hydrolytic stability were obtained.

Mixed zinc–lanthanide metal–organic frameworks based on the 3,5-pyrazoledicarboxylate ligand exhibit an unusual three-dimensional inorganic subnetwork and highly efficient photoluminescence.

Carbonization of zinc containing metal–organic frameworks produces porous carbon materials with an interesting linear relationship between the Zn/C ratio of the precursors and the surface area of the resulting carbon materials.

Reported here is a porous framework constructed from super-supertetrahedral metal–organic clusters and exhibiting four hierarchical levels of supramolecular assembly.

A mixed-linker RHO-type ZIF with Imm symmetry and large pore size is one of four new purine-containing frameworks prepared solvothermally.

A post-synthetic modified core–shell crystal of a porous coordination polymer accumulated aniline derivatives and gave the intense exciplex emission.

A facile in situ nanoparticle seeding method is reported to prepare MIL-101(Cr) films on alumina supports. The in situ seeding of MIL-101(Cr) nanoparticles was promoted by use of dimethylacetamide. The generality of this approach is further demonstrated for Cu₃(btc)₂ films by using a (poly)acrylate promoter.

An upper rim-functionalised calix[4]arene dicarboxylic acid (H₂caldc) has been used to prepare four metal–organic frameworks, three of which have been structurally characterised and shown to form two- or three-dimensional network structures.

We describe a copper(II) containing discrete metal complex gelator able to gel dimethylformamide (DMF) at 0.51 wt%.
