Abstract: A thermally-crosslinked membrane comprising a poly(1,2,4-triazole)-polymer that includes recurring hydroxyl-functionalized triazole units is described. The polymer has the structure of formula I: (I) wherein Ar describes an aromatic or heteroaromatic group, particularly with substituents and/or a multi-ring system, X describes a N group of the formula OR2, wherein R2 is a hydrogen atom or a group with 1 to up to 20 carbon atoms; Y describes a bond or a group with 1 to up to 20 carbon atoms, Z describes a group of the common formula —SO3R1 or —PO(OR1)2, wherein R1 is a hydrogen atom or an alkali metal, and q is a whole number between 0 and 4, wherein n is a natural number ≥10, wherein at least one crosslink is present between two of the hydroxyl-functionalized Ar moieties of the polymer. Methods of making the thermally-crosslinked membranes and separation methods using the thermally-crosslinked membranes are provided.

Abstract: Molecularly porous cross-linked membranes (MPCMs) are described. For example, MPCMs prepared by interfacial polymerization of a reactive macrocycle monomer with intrinsic microporous structure are provided. Macrocycles with multiple reacting sites for cross-linking provide a hyper-cross-linked network suitable for molecular separations employing polar or apolar solvents including organic solvent nanofiltration (OSN).
