Development of new metal-free heterogeneous catalysts has long been the focus of intense research in-terest.The integration of multifunctional monomers into the skeletons of porous organic polymers(POPs)provides an efficient pathway to achieve this goal.Herein,we rationally designed and successfully pre-pared a new Tröger's base(TB)-derived POPs by insertion of pillar[5]arene macrocycle as a positively auxiliary group.Combined the both merits of pillar[5]arene macrocycle and TB moiety,the as-prepared polymer was further explored as an effective metal-free heterogeneous catalyst and exhibited promoted catalytic performance in Knoevenagel condensation and CO2 conversion.This work provides a new strat-egy to fabricate metal-free heterogeneous catalysts based on macrocyclic POPs.
