Correspondence on “Preorganization and Cooperation for Highly Efficient and Reversible Capture of Low‐Concentration CO₂ by Ionic Liquids”

The preorganization and cooperation mechanism of imide-based ionic liquids reported in a recent Communication was evocated to rationalize the extremely high gravimetric CO2 capture displayed by these fluids. An analysis of the reported spectroscopic evidences together with additional experiments led to the proposition of an alternative, simpler, and feasible mechanism involving the formation of bicarbonate.
