Capture of Carbon Dioxide by Cucurbit[7]uril Complex

A supramolecular approach to CO2 capture by cucurbit[7]uril (CB[7]) complex was developed. NH2(CH2)6NH2⊂CB[7] complex can convert CO2 to bicarbonate product exclusively and faster in solution due to the deshielding effect, thereby providing a green absorbent to CO2 with regard to high stability, non-corrosiveness...
