Abstract

A new strategy for multi-molar absorption of CO₂is reported based on activating a carboxylate group in amino acid ionic liquids. It was illustrated that introducing an electron-withdrawing site to amino acid anions could reduce the negative inductive effect of the amino group while simultaneously activating the carboxylate group to interact with CO₂very efficiently. An extremely high absorption capacity of CO₂(up to 1.69 mol mol⁻¹) in aminopolycarboxylate-based amino acid ionic liquids was thus achieved. The evidence of spectroscopic investigations and quantum-chemical calculations confirmed the interactions between two kinds of sites in the anion and CO₂that resulted in superior CO₂capacities.
