Abstract
Methods for preparation of a carbon membrane include providing a solution comprising a diacetyl biphenyl monomer and an alkylsulfonic acid. The solution is treated under such conditions that an aldol condensation reaction occurs so as to produce a porous polymer network. The porous polymer network is treated under such conditions that a Scholl reaction occurs.
