Open AccessCooperative light-induced breathing of soft porous crystals via azobenzene buckling
Although light is a prominent stimulus for smart materials, the application of photoswitches as light-responsive triggers for phase transitions of porous materials remains poorly explored. Here we incorporate ...

Open AccessTowards general network architecture design criteria for negative gas adsorption transitions in ultraporous frameworks
Switchable metal-organic frameworks (MOFs) have been proposed for various energy-related storage and separation applications, but the mechanistic understanding of adsorption-induced switching transitions is st...

Open AccessThe effect of crystallite size on pressure amplification in switchable porous solids
Negative gas adsorption (NGA) in ordered mesoporous solids is associated with giant contractive structural transitions traversing through metastable states. Here, by systematically downsizing the crystal dimen...

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 h...
