Triptycene-based microporous polymer with pending tetrazole moieties for CO2 -capture application

Lei Liu, Jie Zhang
Macromolecular Rapid Communications 2013, 34 (23): 1833-7
Triptycene-based micorporous polymer is functionalized with CO2 -philic tetrazole moieties via ZnCl2 -catalyzed post-polymerization. Gas adsorption experiments indicate that it possesses high CO2 uptake capacity, reaching 134 cm(3) g(-1) (26.5 wt%) at 1.0 bar and 273 K, along with high selectivity towards CO2 over N2 and CH4 . The porous polymeric networks present the promising potentials as efficient adsorbents in clean energy applications.
