Triptycene‐based micorporous polymer is functionalized with CO 2 ‐philic tetrazole moieties via ZnCl 2 ‐catalyzed post‐polymerization. Gas adsorption experiments indicate that it possesses high CO 2 uptake capacity, reaching 134 cm 3 g −1 (26.5 wt%) at 1.0 bar and 273 K, along with high selectivity towards CO 2 over N 2 and CH 4 . The porous polymeric networks present the promising potentials as efficient adsorbents in clean energy applications.
