Nanoporous copolymer networks through multiple Friedel–Crafts-alkylation—studies on hydrogen and methane storage

A novel series of hypercrosslinked copolymer networks was obtained by the statistical co-condensation of 4,4′-bis(chloromethyl)biphenyl with a series of non-functionalized fluorene-based monomers under Friedel–Crafts catalysis. The resulting nanoporous polymer materials exhibit high BET surface areas of up to 1800 m2 g−1 as derived from nitrogen physisorption. The hydrogen and methane uptakes were examined with respect to the chemical composition of these novel polymer adsorbents.
