Effect of gas and vapor sorption on the framework structure of CALF-20

CALF-20 is a chemically and thermally stable metal-organic framework with good carbon dioxide sorption properties even in the presence of water, and it is being evaluated for carbon capture processes. Observations suggest that CALF-20 undergoes significant structural changes depending on the guest molecule in the pores. The aim of the experiment is to investigate the structural response of CALF-20 towards relevant adsorptives.
