The invention relates to a hydrogen-bonded organic framework (HOF) comprising at least one kind of organic linker with at least one functional group forming a hydrogen-bonded network, wherein the functional group comprise a hydroxyl group and a central atom of tetrahedral geometry, and wherein the HOF is semi-conductive, proton-conductive and porous, preferably microporous. In embodiments, the at least one functional group is selected from the group comprising phosphonic acid, phosphinic acid, arsonic acids, arsinic acids, phosphonate, arsonate and/or esters thereof comprising at least one hydroxylgroup. The invention further relates to a covalent organic framework (COF), characterized in that it has been generated from a HOF according to any of the preceding claims by transforming the hydrogen bonds between the functional groups into covalent anhydride bonds via a condensation reaction or reactions known to form anhydrides.
