Knitting polycyclic aromatic hydrocarbon-based microporous organic polymers for efficient CO₂ capture.

ABSTRACT: In order to achieve efficient CO₂ capture, four novel microporous organic polymers, based on distinct polycyclic aromatic hydrocarbons such as fluoranthene, binaphthalene, naphthalene and phenanthrene, were successfully prepared by the solvent knitting method. N₂ sorption isotherms indicate that these polymers are predominately microporous with ultrahigh BET surface area i.e., 1788 m² g^-1 for fluoranthene-based Polymer 1, 1702 m² g^-1 for binaphthalene-based Polymer 2 and objective CO₂ uptake capacity of 24.79 wt% and 20.19 wt% (273.15 K/1.00 bar) respectively. While compared with the former two polymers, though 1227 m² g^-1 and 978 m² g^-1 are moderate in surface ar
