An ionic liquid composition having the following chemical structural formula: wherein R1, R2, R3, and R4 are independently selected from hydrocarbon groups containing at least 1 and up to 20 carbon atoms, and X- is a cyclic anion that possesses a negatively-charged group reactive with a gaseous electrophilic species, particularly carbon dioxide or sulfur dioxide. Methods for capturing a gaseous electrophilic species, such as CO2 or SO2, by contacting the gaseous electrophilic species with an ionic liquid according to Formula (1) are also described.

A novel strategy for SO(2) capture throughmultiple-site absorption in the anion of several azole-based ionicliquids is reported. An extremely high capacity of SO(2) (>3.5 mol/mol) and excellent reversibility (28 recycles) were achieved by tuning the interaction between the basic anion and acidic SO(2). Spectroscopic investigations and quantum-mechanical calculations showed that such high SO(2) capacity
