Abstract
A new series of porous organic networks (PONs) internally decorated with several free –OH functional groups has been synthesized through acid catalyzed condensation reaction of terephthalaldehyde and nucleophilic aromatic compounds. These materials possess high Brunauer–Emmett–Teller specific surface areas (592–865 m2 g−1) and showed maximum CO2 adsorption capacity of 4.31 mmol g−1 and H2 uptake of 8.23 mmol g−1 at 273 and 77 K, respectively, under 1 bar.
