摘　　要：N-heterocyclic carbene(NHC) is a potent organic small-molecule catalyst.However,its high synthetic price and frequent use in combination with excess oxidants have limited its utilization in industrial production.We designed and synthesized a porous organic polymer with NHC as the core structure to solve the above problems.The catalytic performance of the polymer was tested in this work.The polymer can successfully catalyze the cycloaddition reaction of aldehyde and ethyl isocyanoacetate under electro-oxidation.The results showed that the polymer catalyst can be recycled and had higher catalytic activity than homogeneous NHC.The developed catalytic system(organic electrochemistry and NHC polymer) solves the existing problems of NHC catalysis and provides a reference for the development of new green catalytic systems.
