hysteresis of intrusion–extrusion of mercury observed in MIL-53(Cr) particles is interpreted as the transition from large-pore to narrow-pore forms of this metal–organic framework (MOF) material, provoked by the isostatic pressure created by mercury around the porous particles. The observed behavior may be qualitatively explained by a simple energetic model and opens possibilities for applications as dampers or molecular springs.
