摘要：

A critical analysis of the role of Hammett basicity (H-) and aqueous basicity (pK(a)) in CO2 uptake in deep-eutectic solvents (DESs) suggests that neither H- nor pK(a) correlates with the CO2 w/w% capacity in the studied DESs. Instead, strong "synergistic interactions" between donor and acceptor moieties satisfactorily relate to the w/w% of CO2 in DESs.
