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.
