A novel porous aromatic framework, PAF-8, derived from tetraphenylsilane as basic building unit, was successfully synthesized via Friedel–Crafts alkylation reaction. This PAF material had high thermal stability as well as high surface area (785 m² g⁻¹) calculated from the Brunauer–Emmett–Teller (BET) model. Meanwhile, PAF-8 possessed high performances in gas sorption and especially for CO₂ separation.
