A hierarchical meso-macroporous poly(ionic liquid) monolith with tunable pore structure is synthesized through free radical self-polymerization of 1-allyl-3-vinylimidazolium ionic liquid by using the tri-block copolymer P123 as the soft template. The obtained polymeric matrix can highly disperse heteropolyanions through anion-exchange, exhibiting superior catalytic activity in cis-cyclooctene epoxidation with H2O2.
