Conductive polymer with side chain containing TEMPO as well as preparation method and application of conductive polymer

The invention relates to the technical field of electrochemistry, and discloses a conductive polymer with a side chain containing TEMPO as well as a preparation method and application of the conductive polymer. At present, 2, 5-diformyl furan prepared from 5-hydroxymethylfurfural as a raw material has the problem that a catalyst is difficult to recover and a product is difficult to separate. In order to solve the technical problem, a micromolecular catalyst TEMPO is connected to a conductive polymer, and the conductive polymer obtained through connection realizes heterophase electrochemical catalytic oxidation of 5-hydroxymethylfurfural by TEMPO to generate 2, 5-diformyl furan. The conductive polymer is used as a catalyst for preparing 2, 5-diformyl furan through electrocatalytic oxidation of 5-hydroxymethylfurfural, the problem that the catalyst and a product are difficult to separate is solved, and meanwhile the conductive polymer has the advantages of being high in reaction rate and product yield. 本发明涉及电化学
