Low‐density, solid‐state, porous supramolecular organic frameworks are constructed using pillarenes. The frameworks have a honeycomb‐like structure, permanent porosity, high thermal stability, and selective and reversible sorption properties toward CO 2 . The exceptionally selective CO 2 ‐sorption properties (375/1, 339/1) of one framework over N 2 and CH 4 indicate potential applications in CO 2 ‐capture for post‐combustion power plants and natural gas sweetening.
