Abstract

Polycarbazoles with rigid skeletons and electron-rich conjugated systems are beneficial to form permanent porous materials with intrinsic photoelectric properties. In recent years, the research related to porous polycarbazoles becomes a hot topic in the field of porous organic polymers. The preparation methods for porous polycarbazoles are diverse, commonly represented by the oxidation coupling reaction and the Friedel-Crafts reaction. Other methods such as nitrile-based trimerization, electrochemical polymerization, and classic C-C coupling reactions are also reported. Porous polycarbazoles generally possess large specific surface area, permanent pore structure, and high thermal and chemical stability, which show potential applications in gas storage and separation, catalysis, sensors, and electronics. In this review, the recent research progress on the synthetic methods, functions, and applications of porous polycarbazoles is summarized.
