Abstract We proposed a new strategy to maximize the density of acidic groups by modulating electronic effects substituents for high‐performance proton conductors. The conductivity sulfonated 1‐MeL40‐S with methyl group corresponds 2.29×10 −1 S cm at 80 °C and 90 % relative humidity, remarkably an 22100‐fold enhancement over nonsulfonated 1‐MeL40 . maintains long‐term one month. confirm that this synthetic method is generalized extended version POPs, 2‐MeL40‐S 3‐MeL40‐S In particular, conductivities POPs compete those top‐level porous organic Moreover, activation energy lower than top‐performing materials. This study demonstrates systematic alteration useful route improve durability proton‐conducting
