Abstract: To improve the proton conduction of crystalline porous organic salts(CPOS-1), H2SO4 and H3PO4 were introduced into the channel to obtain H2SO4@CPOS-1 and H3PO4@CPOS-1. Compared to CPOS-1, the proton conductivities of H2SO4@CPOS-1 and H3PO4@CPOS-1 increased two orders of magnitude and one order of magnitude at 303 K and 100% RH, respectively. It can be attributed to the increasing concentration of the protons, which dissociates from the acids.

Key words: Proton conductivity, Crystalline porous organic salt, H2SO4, H3PO4
