SO<sub>2</sub> Capture Using Porous Organic Cages.
ANGEWANDTE CHEMIE-INTERNATIONAL EDITION, 60 (32).
pp. 17556-17563.
Abstract
We report the first experimental investigation of porous organic cages (POCs) for the demanding challenge of SO<sub>2</sub> capture. Three structurally related N-containing cage molecular materials were studied. An imine-functionalized POC (CC3) showed modest and reversible SO<sub>2</sub> capture, while a secondary-amine POC (RCC3) exhibited high but irreversible SO<sub>2</sub> capture. A tertiary amine POC (6FT-RCC3) demonstrated very high SO<sub>2</sub> capture (13.78 mmol g<sup>-1</sup> ; 16.4 SO<sub>2</sub> molecules per cage) combined with excellent reversibility for at least 50 adsorption-desorption cycles. The adsorption behavior was investigated by FTIR spectroscopy, <sup>13</sup> C CP-MAS NMR experiments, and computational calculations.
