Steric bulk controls CO 2 absorption : N‐substituted amino acid salts in poly(ethylene glycol) reversibly absorb CO 2 in nearly 1:1 stoichiometry. Carbamic acid is thought to be the absorbed form of CO 2 ; this was supported by NMR and in situ IR spectroscopy, and DFT calculations. The captured CO 2 could be converted directly into oxazolidinones and thus CO 2 desorption could be sidestepped.
