  • 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.

  • Although hydrogen gas could serve as a promising future fuel, its high-capacity storage is a challenge. Now, a nanoporous magnesium borohydride framework is shown to store hydrogen as densely packed penta-dihydrogen clusters having well-defined orientations and directional interactions with the framework.

  • The application of photoswitches as light-responsive triggers for phase transitions of porous materials remains poorly explored. Here, the authors report a light-responsive flexible metal-organic framework which undergoes pore contraction upon combined application of light irradiation and adsorption stress via a buckling process of the framework-embedded azobenzene photoswitch.

  • Pressure amplification phenomena have recently been observed in ordered mesoporous solids, but little is understood about this counter-intuitive behaviour. Here, Kaskel and colleagues demonstrate that crystal size can play an important role in modulating pressure amplification in metal-organic frameworks.

  • Porous framework material DUT-49 was recently demonstrated to exhibit a unique counterintuitive negative gas adsorption (NGA) behaviour. Here the authors identify framework DUT-50 as an additional pressure amplifying material that features distinct NGA transitions, and suggest structural design criteria to access other such materials.
