Fig. 7. (a) Schematic structures of the porous liquid and analogous porous solids. CC1α packs in a window-to-arene fashion and contains only isolated voids within the cage itself (grey = core cage structure; orange = isolated cage voids). Solid, scrambled 3³:13³-R (not illustrated) will have the same cage cavities, but will also have some degree of extrinsic porosity between cages. Crystalline CC3-R and CC13 have interconnected pore networks (yellow); crystalline CC13 also has some formally isolated cage voids (orange); grey = core cage structure; red = cyclohexane vertices; pink = methylpropane vertices; (b) gas sorption isotherms for solid scrambled 3³:13³-R cages at 293 K; (c) gas sorption isotherms for solid CC1α at 293 K, shown on the same scale; the material can adsorb gases at this temperature despite its lack of formally connected pore channels; (d) comparison of the molecular equivalents of gas per cage for the porous liquid, calculated from the amount of gas evolved, and for both the solid scrambled 3³:13³-R cage and CC1α, as determined by gas sorption measurements.
