A ligand insertion mechanism for cooperative NH3 capture in metal–organic frameworks
A three-dimensional metal–organic framework reversibly binds ammonia by cooperative insertion into its metal–linker bonds to form a dense, one-dimensional coordination polymer, enabling high-capacity ammonia uptake with intrinsic thermal management.

Asymmetric pore windows in MOF membranes for natural gas valorization
A metal–organic framework membrane based on fumarate and mesaconate linkers is shown to have a pore aperture shape that enables efficient and cost-effective removal of nitrogen and carbon dioxide from methane.

Orthogonal-array dynamic molecular sieving of propylene/propane mixtures
A dynamic molecular sieve made from a metal–organic framework with orthogonally arrayed pockets is capable of separating propylene (C3H6) from a propylene (C3H6)/propane (C3H8) gas mixture.

Filling metal–organic framework mesopores with TiO2 for CO2 photoreduction
Investigation of a chromium-based metal–organic framework shows that the location of added TiO2 inside specific mesopores strongly affects the ability of the material to catalyse photoreduction of CO2.

Data-driven design of metal–organic frameworks for wet flue gas CO2 capture
Data mining of a computational library of metal–organic frameworks identifies motifs that bind CO2 sufficiently strongly and whose uptake is not affected by water, with application for the capture of CO2 from flue gases.

Confinement of atomically defined metal halide sheets in a metal–organic framework
The pore space in the metal–organic framework Zr6O4(OH)4(bpydc)6 can be used as a scaffold to grow precisely defined atomically thick sheets of metal halide materials, taking advantage of multiple binding sites to direct complexation of the metal ions; these metal halide nanosheets fill the size gap between discrete molecular magnets and bulk magnetic materials, with potentially unusual magnetic properties arising from this size regime.

Chemical control of structure and guest uptake by a conformationally mobile porous material
A new metal–organic framework has several conformational degrees of freedom that can be modified by the external chemical environment to change the structure and trigger the uptake of a guest molecule.

Predicting crystal growth via a unified kinetic three-dimensional partition model
A general simulation approach that can replicate, and in theory predict, the growth of a wide range of crystal types, including porous, molecular and ionic crystals, is demonstrated.

A pressure-amplifying framework material with negative gas adsorption transitions
For adsorption processes, gas uptake usually increases with increasing pressure; however, here the phenomenon of negative gas adsorption is demonstrated in a metal–organic framework, which undergoes a sudden hysteretic structural deformation and pore contraction, releasing guest molecules.

Extra adsorption and adsorbate superlattice formation in metal-organic frameworks
Metal-organic frameworks have a porous structure that has useful applications in gas adsorption; here, small-angle X-ray scattering is used to visualize the process of adsorption as gas pressure increases, revealing that adsorbate molecules interact across pore walls in a way that allows extra adsorbate domains to be created in the framework and to form superlattices, before the adsorbate settles down into a more uniform distribution.

The crystallography of correlated disorder
Although classical crystallography is insufficient to determine disordered structure in crystals, correlated disorder does nevertheless contain clear crystallographic signatures that map to the type of disorder, which we are learning to decipher.
