Content summary:
Self-porous polymer is a kind of organic porous material formed by using molecular design method, which links specific elements with geometrical shape through covalent bond and destroys polymer condensed state. It has the characteristics of flexible structure design, free adjustment of pore channels and rich modification of pore surface. As optoelectronic materials or carbon precursors, self-porous polymers have great potential applications in environmental remediation, catalysis and clean energy. As a typical representative, nitrogen-conjugated microporous macromolecules have attracted particular attention due to their unique polarization and REDOX properties. We propose the design and synthesis of a series of nitrogen-containing conjugated microporous macromolecules with main chains, and optimize their specific surface area, porosity and selective gas adsorption by adjusting the building units and functional groups. Using its unique REDOX activity and abundant porous structure, the supercapacitor is constructed, which has the advantages of high capacity, high power density, high cycle stability and fast charging. This paper mainly reports the research progress of self-contained porous polymers, carbon and iodine capture and electrochemical energy storage in the past five years.
