A series of trihydroxy-substituted aromatic azo compound construction units (named as Azo-R, R = NHBoc, NH2, p-pherol-NHBoc, CHO, B(OH)2, CN or CH2CN) are prepared by using a step-by-step synthesis strategy, and then are used as precursors to synthesize a series of stable, high-crystallinity and high-specific-surface-area novel covalent organic framework (COFs) materials. Characterization resultsshow that the COFs have a high specific surface area and an excellent chemical stability, and are stable in various common organic solvents (acetone, dichloromethane, DMF and the like), concentrated hydrochloric acid (12 M), concentrated alkali NaOH (12 M) and boiling water. In addition, good hydrophilicity and high water vapor adsorption capacity of the materials make the COFs become an ideal proton conducting material. After phosphoric acid is loaded, the COFs achieve ultrahigh proton conductivity, and the conductivity can reach 1.13 * 10<-1> S / cm, and can be comparable with the value (~1.1* 10<-1> S / cm) of commercial Nafion. The COFs can be easily processed to form a proton exchange membrane device and applied to hydrogen-oxygen fuel cells.
