SO(2) Capture Using Porous Organic Cages

We report the first experimental investigation of porous organic cages (POCs) for the demanding challenge of SO(2) capture. Three structurally related N‐containing cage molecular materials were studied. An imine‐functionalized POC (CC3) showed modest and reversible SO(2) capture, while a secondary‐a...

description We report the first experimental investigation of porous organic cages (POCs) for the demanding challenge of SO(2) capture. Three structurally related N‐containing cage molecular materials were studied. An imine‐functionalized POC (CC3) showed modest and reversible SO(2) capture, while a secondary‐amine POC (RCC3) exhibited high but irreversible SO(2) capture. A tertiary amine POC (6FT‐RCC3) demonstrated very high SO(2) capture (13.78 mmol g(−1); 16.4 SO(2) molecules per cage) combined with excellent reversibility for at least 50 adsorption–desorption cycles. The adsorption behavior was investigated by FTIR spectroscopy, (13)C CP‐MAS NMR experiments, and computational calculations.
