This study conducted the first experimental investigation on porous organic cages (POCs) for capturing SO2. It was found that a tertiary amine POC (6FT-RCC3) exhibited high and reversible SO2 capture, demonstrating excellent performance for at least 50 adsorption-desorption cycles. The adsorption behavior was analyzed using FTIR spectroscopy, C-13 CP-MAS NMR experiments, and computational calculations.
We report the first experimental investigation of porous organic cages (POCs) for the demanding challenge of SO2 capture. Three structurally related N-containing cage molecular materials were studied. An imine-functionalized POC (CC3) showed modest and reversible SO2 capture, while a secondary-amine POC (RCC3) exhibited high but irreversible SO2 capture. A tertiary amine POC (6FT-RCC3) demonstrated very high SO2 capture (13.78 mmol g(-1); 16.4 SO2 molecules per cage) combined with excellent reversibility for at least 50 adsorption-desorption cycles. The adsorption behavior was investigated by FTIR spectroscopy, C-13 CP-MAS NMR experiments, and computational calculations.
