Abstract

Abstract: We demonstrate the facile microwave‐assisted synthesis of a porous organic framework1 and the sulfonated solid (1S ) through postsubstitution. Remarkably, the conductivity of1S showed an approximately 300‐fold enhancement at 30 °C as compared to that of1, and reached 7.72×10 −2 S cm −1 at 80 °C and 90 % relative humidity. The superprotonic conductivity exceeds that observed for any conductive porous organic polymer reported to date. This material, which is cost‐effective and scalable for mass production, also revealed long‐term performance over more than 3 months without conductivity decay.
