Separation of CO₂ from gas mixtures is a major application focus for porous materials. Now it has been shown that fluorinated non-porous crystalline materials can uptake CO₂ via mobile perfluoroalkyl regions, a process resembling the dissolution of CO₂ in perfluoroalkanes, while CH₄ uptake is hindered. In situ X-ray diffraction data provide insight into the sorption process.
