Abstract

Chemistry in motion: A combination of confocal microscopy (see picture) and reaction-diffusion modeling provided a powerful toolkit with which solution transport into metal–organic framework crystals was studied. Commonly used pure diffusion models are insufficient to describe this process and, instead, it is necessary to account for the interactions of the guest molecules and the MOF scaffold.
