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.
我们展示了一种含有全氟芳环的多孔有机[4+4]亚胺笼的合成。气体吸附实验表明，对于直接从反应混合物中获得的晶体材料，其比表面积为536 m² g⁻¹，在273 K和1 bar下对CO₂的吸附量为19.0 wt%（4.2 mmol g⁻¹），在77 K和1 bar下对H₂的吸附量为1.5 wt%（7.5 mmol g⁻¹），同时具有出色的热稳定性，使其成为一种非常有趣的适用于气体吸附的多孔材料。
