Amine or Azo functionalized hypercrosslinked polymers for highly efficient CO2 capture and selective CO2 capture

Hypercrosslinked polymers (HCPs) are very promising for large-scale applications due to their easy preparation, high thermal stability, and good capability of CO2 capture. Currently, many amine-functionalized porous materials prepared through two steps. In this paper, the HCPs was obtained with a one-step method it showed adsorption up 4.24 mmol/g at 273.15 K. addition, since azo-functionalized have potential like photoresponsive ‘smart’ materials, azobenzene is an attracting functional group development materials. Herein, firstly reported, used as adsorbents (3.02 K) performing CO2/N2 selectivity (34.52 298.15 K).
