Abstract: Two-dimensional covalent organic frameworks (2D COFs) have attracted much attentions in proton conduction, owing to their regular pore channels and easy functionalization. However, most of COFs required the loading of proton carriers to achieve high proton conductivity. Here, we report the immobilization of flexible sulfonic acid groups on the channel walls of PyTTA-DHTA-COF (synthesized by condensation of 4,4',4'',4'''-(pyrene-1,3,6,8-tetrayl)tetraaniline and 2,5-dihydroxyterephthalaldehyde) via a simple post-synthetic modification strategy. The sulfonated COF showed intrinsic proton conductivity up to 10^-3 at 25 °C and 100% relative humidity (RH), and high conductivity up to 10^-2 S cm^-1 under at 70 °C and 100% RH without introduction of any non-covalent acid molecules or imidazole derivatives.
