The　capture　and　conversion　of　CO2　into　value-added　chemicals　has　become　an　imminent　research　topic　in　both　scientific　and　industrial　area.　The　cycloaddition　of　CO2　with　C1　resource　such　as　epoxides　to　produce　cyclic　carbonates　is　an　promising　and　efficiency　pathway　for　CO2　utilization.　The　development　of　catalyst　for　CO2　cycloaddition　with　epoxides　at　low　pressure　is　still　a　challenge.　Herein,　we　reported　the　preparation　of　cyclic　polypyrazoles　integrated　with　bromoethane,　which　can　serve　as　hydrogen　bonding　donor　and　nucleophilic　groups,　respectively,　for　activation　of　the　epoxides　and　subsequent　cycloaddition　of　CO2.　The　as-obtained　ionic　cyclic　polypyrazoles　(ICPP)　could　exist　in　the　form　of　polymetric　pseudo　liquid　during　reaction　and　then　turns　into　heterogenous　state　after　reaction　due　to　the　low　glass　transition　temperature.　By　changing　the　reaction　temperature　and　ratio　of　catalyst　to　epoxides,　an　optimized　performance　which　show　a　epoxides　conversion　over　90　%　and　a　selectivity　of　99　%　to　cyclic　carbonate　was　realized　under　0.1　MPa　in　the　absence　of　cocatalysts　and　additives.　The　catalyst　can　be　facilely　recovered　due　to　its　high　stability,　and　no　obvious　decrease　in　conversion　was　observed　after　five　successive　runs.　This　work　provides　a　sustainable　and　green　process　for　CO2　cycload-dition,　and　also　highlights　the　potential　of　using　ionic　cyclic　polypyrazole　for　conversion　of　CO2　into　value-added　chemicals.
