Abstract
Three new carbazole containing cross-linked polymers namely AH-Poly, TM-PDA-Poly and TMB-PDA-Poly were designed and successfully synthesized by an oxidative polymerization protocol. The prepared AH-Poly showed a specific BET surface area of 822 m2 g?1 and 10.6 wt% CO2 gas adsorption at 273 K. Moreover, two imide linked PDA-polymers exhibited a significantly excellent specific surface area of 1459–1691 m2 g?1 and possess excellent CO2 adsorption capacity of 19 wt% and 12 wt% at 273 K and 295 K, respectively. This work proposed that the design of monomer with carbazole as the network core, imide bonds and heteroatom enrichment promotes the fabrication of very stable and highly efficient microporous polymers with high CO2 absorption capacities.
