Poly(ionic liquid)s with unique adsorption-swelling ability toward epoxides for efficient atmospheric CO 2 conversion under cocatalyst-/metal-/solvent-free conditions

Poly(ionic liquid)s with unique adsorption-swelling ability to epoxides are facilely synthesized via free radical polymerization in water, serving as highly efficient heterogeneous catalysts for atmospheric CO 2 cycloaddition under mild conditions.
