Metal-organic frameworks have a porous structure that has useful applications in gas adsorption; here, small-angle X-ray scattering is used to visualize the process of adsorption as gas pressure increases, revealing that adsorbate molecules interact across pore walls in a way that allows extra adsorbate domains to be created in the framework and to form superlattices, before the adsorbate settles down into a more uniform distribution.
