Abstract

We present the synthesis of two porous complementary tetrahedral Tri⁴Tri⁴ imine cages, exhibiting Brunauer–Emmett–Teller (BET) surface areas of 591 m² g⁻¹ and 753 m² g⁻¹, suitable for the adsorption of H₂, CO₂, and CH₄. Comparisons in terms of crystallinity, thermal stability, porosity, and selectivity highlight the promising properties of fluorinated and non-fluorinated porous organic cages as functional materials.
