Flexibility of ZIF-8 materials studied by 129 Xe NMR


Springuel, M.-A., et al., Flexibility of ZIF-8 materials studied by 129 Xe NMR. Chemical Communications, 2013.


Structural changes of porous hybrid inorganic-organic ZIF-8 compound has been explored by hyperpolarized 129Xe NMR of adsorbed xenon at various temperatures. Upon xenon adsorption at low temperature, the organic linkers undergo a reorientation leading to a stepwise increase in xenon adsorption and in chemical shift
