Abstract Separation of CO2 from gas mixtures is important in applications such as CH4 gas purification and blue hydrogen production. Here we report selective CO2 uptake by a family of flexible silver coordination polymers (AgCPs) that are ostensibly non-porous but exhibit latent porosity to CO2 above a gate pressure, through a mechanism akin to dissolution in fluoroalkanes.

Metal–organic frameworks (MOFs) are crystalline solid materials that consist of inorganic nodes (either metal ions or secondary-building units (SBUs) based on metal-containing clusters) coordinatively bonded to organic ligands (linkers) in a three-dimensional porous network. They have been gaining increasing interest from researchers in recent years, with the field growing rapidly since the 1990s.
