Themed collection Cooperative phenomena in framework materials

A brief summary and personal perspectives on the virtual Faraday Discussion: Cooperative Phenomena in Framework Materials (13–16 October 2020).

Quartz-type MOF (Me₂NH₂)₂[Cd(NO₂BDC)₂] (SHF-81) exhibits anisotropic breathing behaviour as single crystals in response to multiple stimuli.

We provide a brief overview of the state of the MOF field from their inception to their synthesis, potential applications, and finally, to their commercialization.

A series of anionic zinc-based MOFs have been prepared and electron transfer reactions involving the viologen counter-cations studied.

Here, we study the thermal stability of ten 2D covalent organic frameworks using a combination of variable-temperature X-ray diffraction, thermogravimetric analysis, diffuse reflectance infrared spectroscopy, and density-functional theory.

MOF-FF was fitted for flexible linkers and used to investigate the breathing phase transition of MOFs with flexible side-chains.

Adsorption-induced contraction and negative gas adsorption in the mesoporous metal–organic framework DUT-49 for different gases and temperatures.

MOFs UiO-68 and PCN-57, containing triphenylene linkers, were doped with a tetracarboxylate linker that contains a [2]rotaxane molecular shuttle, and VT CP MAS ¹³C SSNMR was used to explore the motion of the macrocyclic ring inside the cavities.

The cooperative phenomenon between proton conduction and vapochromism of luminescent Pt(II) complexes, [PtCl(tpypy)]Cl and [PtCl(tpypyH)]Cl₂, is reported.

This paper describes the cost-efficient and scalable synthesis and shaping processes of Al(OH)-fumarate beads of various sizes appropriate for use in water Adsorption Heat-Pumps (AHPs).

The chiral pore-surface of a porous metal–macrocycle framework face-selectively adsorbs a prochiral molecule with the aid of a supramolecular chiral auxiliary.

A 3D porous MOF containing a tripodal nitrile ligand was found to show crystal melting at 271 °C and vitrification.

We develop the concepts of combinatorial mechanics, adaptive flexibility, and error-correcting codes as applications of disordered framework materials.

A porous organic cage crystal, α-CC2, shows unexpected adsorption of sulphur hexafluoride (SF₆) in its cage cavities, which was investigated and rationalized using in situ diffraction and molecular simulations.

Insight into the heat transport and water-adsorption properties of the flexible MIL-53(Al) is obtained using advanced molecular dynamics simulations.

This work showcases the first instance of cooperative photoelectrochemical oxidation within a chromophore/catalyst-incorporated metal–organic framework.

Structure determination by continuous rotation electron diffraction can be as feasible and accurate as single crystal X-ray diffraction without the need for large crystals.

Simulations reveal the influence of rotating molecular motors and the importance of orientation and directionality for altering the transport properties of fluids. This has outlined that motors with specific rotation can generate directed diffusion.

Melting, glass formation, amorphisation and crystallisation were confirmed in coordination polymers and metal–organic frameworks by differential scanning calorimetry.

Preordering of the linker site and utilising framework flexibility are critical to achieving high levels of metal loading during post-synthetic metalation.

Molecular motions taking place in the nanospace of metal–organic frameworks (MOFs) are an interesting research subject, although not yet fully investigated.

Through the here introduced micromechanical equations of state, long-range dynamic phenomena in MOFs can be investigated starting from atomistic information.
