This letter reports the fabrication of a three-dimensional hydroxy-rich nanoporous framework PAF-P5-OH, which exhibits excellent CO2 uptake capacity due to the dipole interactions between the adsorbed CO2 molecules and the hydroxy groups in PAF-P5-OH.
In this letter, we report our fabrication of a three-dimensional hydroxy-rich pillar[5]arene-extended nanoporous aromatic framework PAF-P5-OH for CO2 uptake. CO2 adsorption study demonstrated that PAF-P5-OH exhibited excellent CO2 uptake capacity (88 cm3 g-1 at 273 K and 76 cm3 g-1 at 298 K) under atmospheric pressure, which could be attributed to the favored dipole interactions between the adsorbed CO2 molecules and the hydroxy groups in PAF-P5-OH.
