Self-diffusion coefficients measured using a high-gradient part of the attenuation curves at 298 K and plotted as a function of pressure (a) and loading per unit cell (b). The data for DUT-49(Cu) are taken with permission from ref. 37. and shown for comparison. Green shading highlights area of non-equal diffusivities for comparable loadings captured upon sorption and desorption. Adsorption of n-butane in DUT-149(Cu) (blue symbols) (c) and DUT-49(Cu) (red symbols) (d) at 298 K and evolution of unit cell parameters upon adsorption experiment (purple symbols).
