Fig. 11. (A) Four types of porous liquids compared to conventional non-porous liquids. Type I: neat liquid hosts that cannot collapse or interpenetrate. Type II: empty hosts dissolved in sterically hindered solvents. Type III: framework materials dispersed in hindered solvents. Type IV: porosity retention in melt state of CPs/MOFs. (B) Sorption isotherms of non-responsive (blue) and responsive (red) porous solids. (C) Isothermal gas uptake of porous liquids with non-responsive CP/MOF particles (blue) and responsive CP/MOF particles (red). Maximum adsorption pressure (pmax) and minimum desorption pressure (pmin) for a pressure swing are indicated by dashed vertical grey lines. Adapted with permission from ref. 127.
