Time-resolved femtosecond crystallography (TR-SFX) is a powerful technique to monitor structural transitions in protein crystals at the atomic level, but its use in non-protein synthetic materials remains limited. Now TR-SFX has been used to visualize the structural dynamics of metal–organic frameworks, showing the potential of this tool to study the dynamic motion of crystalline porous materials.

C–H···π interactions disrupt electrostatic interactions between non-aqueous electrolytes to increase solubility
The energy density in redox flow batteries is currently limited by the solubility of dissolved redox species. Now it has been shown that intermolecular C–H···π interactions can disrupt electrostatic forces in these organic electrolytes to improve their solubility in non-aqueous solvents.

Isotherms of individual pores by gas adsorption crystallography
Gas sorption studies in porous materials typically reflect their overall gas uptake. Now, using a ‘gas adsorption crystallography’ method, the gas adsorption isotherms of two metal–organic frameworks (MOFs) have been quantitatively decomposed into sub-isotherms that reflect the pore-filling behaviour of various guests in the different types of pores present in the MOFs.

Capturing snapshots of post-synthetic metallation chemistry in metal–organic frameworks
Obtaining precise structural information for metal-centred reactions that take place within the pores of metal–organic frameworks continues to be an elusive goal. Now, a flexible framework has been synthesized that enables the direct elucidation of the products of post-synthetic metallation reactions and subsequent chemical transformations by single-crystal X-ray crystallography.

Anisotropic oxygen diffusion at low temperature in perovskite-structure iron oxides
The movement of oxygen ions through materials is important in electrolytes and separation membranes, but is rare at lower temperatures. Two different low-temperature diffusion pathways are revealed during the reduction process of CaFeO2.5 to CaFeO2. The two pathways are significantly different, resulting in anisotropy.
