Because　CO2　is　the　main　greenhouse　gas,　its　capture　and　catalytic　conversion　are　thought　to　be　significant　issues　to　be　solved　at　the　current　time.　Given　the　thermodynamically　stable　and　inert　nature　of　CO2,　it　is　highly　desirable　to　develop　advanced　catalysts　to　facilitate　the　transformation　of　CO2　to　other　high-value-added　chemicals　under　mild　conditions.　Within　this　regard,　porous　organic　polymers　(POPs),　featuring　large　surface　areas,　high　thermal　stabilities,　diverse　building　blocks,　and　tunable　porous　structures,　are　an　ideal　platform　for　the　construction　of　heterogeneous　catalysts　for　CO2　conversion.　Incorporating　active　sites　that　are　capable　of　activating　CO2　and/or　substrates　into　the　frameworks　of　POPs　can　facilitate　CO2　conversion.　In　this　Review,　the　most　recent　advances　in　the　design　and　synthesis　of　POP-based　heterogeneous　catalysts　for　the　conversion　of　CO2　are　summarized.　We　mainly　focus　on　the　synthetic　strategies　researchers　have　used　for　incorporating　active　sites　into　POP　frameworks　to　prepare　heterogeneous　catalysts　for　CO2　conversion,　including　N-doping,　metalation,　and　ionic　functionalization.　Problems　remaining　to　be　addressed　in　this　field　are　analyzed,　and　future　directions　are　outlined.　©　2018　American　Chemical　Society.
