Abstract

Two microporous covalent triazine-based frameworks (CTFs) with triptycene (TPC) and fluorene (FL) backbones have been synthesized through a mild AlCl₃-catalyzed Friedel–Crafts reaction, with the highest surface area of up to 1668 m² g⁻¹ for non-ionothermal CTFs. CTF-TPC and CTF-FL show an excellent carbon dioxide uptake capacity of up to 4.24 mmol g⁻¹ at 273 K and 1 bar.
