Xenon adsorption-induced flexibility of the zeolitic imidazolate framework ZIF-4 observed by in situ129Xe NMR spectroscopy
{{output}}
In situ 129Xe NMR spectroscopy reveals an unexpected, xenon adsorption-induced flexibility of ZIF-4. Beyond a certain threshold pressure, xenon induces a structural transition at low temperature. This behaviour is in contrast to CO2, where the material remains... ...
