Maximizing the ionic liquid content and specific surface area in hierarchically nanoporous hypercrosslinked poly(ionic liquid)s towards the efficient conversion of CO₂ into cyclic carbonates

Abstract

Nanoporous poly(ionic liquid)s with both great porosities and high IL contents are prepared through a two-step synthetic strategy, serving as efficient heterogeneous catalysts for CO 2 cycloaddition with epoxides under mild conditions.
