We present the synthesis of a porous, organic [4+4] imine cage containing perfluorinated aromatic panels. Gas adsorption experiments show an uptake of 19.0 wt% CO2 (4.2 mmol g−1, 273 K and at 1 bar) and 1.5 wt% H2 (7.5 mmol g−1, 77 K and at 1 bar) for the specific surface area of 536 m2 g−1 of the crystalline material obtained directly from the reaction mixture, combined with an outstanding thermal stability, making it a very interesting porous material suitable for gas adsorption.
