Microporous Polymers from a Carbazole-Based Triptycene Monomer: Synthesis and Their Applications for Gas Uptake

Two kinds of novel organic microporous polymers TCPs (TCP-A and TCP-B) were prepared by two cost-effective synthetic strategies from the monomer of tricarbazolyltriptycene (TCT). Their structure and properties were characterized by FT-IR, solid (CNMR)-C-13, powder XRD, SEM, TEM, and gas absorption measurements. TCP-B displayed a high surface area (1469m(2)g(-1)) and excellent H-2 storage (1.70wt% at 1bar/77K) and CO2 uptake abilities (16.1wt% at 1bar/273K), which makes it a promising material for potential application in gas storage.
