Hypercrosslinked polymer networks were synthesized by the self-condensation of bischloromethyl monomers such as dichloroxylene (DCX), 4,4'-bis(chloromethyl)-1,1'-biphenyl (BCMBP), and 9,10-bis(chloromethyl)anthracene (BCMA). These materials are predominantly microporous and exhibit BrunauerEmmett-Teller (BET) surface areas of up to 1904 m2/g as measured by N2 adsorption at 77.3 K (Langmuir surface area = 2992 m2/g). Networks based on BCMBP exhibit a gravimetric storage capacity of 3.68% at 15 bar and 77.3 K - the highest yet reported for an org. polymers. The challenges presented by this approach - in particular, in designing strategies to produce materials which physisorb H at more practicable temps. are discussed.
