1. A method comprising:
depositing a hexaiodo-substituted macrocycle onto a substrate comprising a Ag(111) surface;
coupling the macrocycle to form a nanoporous graphene sheet;
layering the nanoporous graphene sheet and substrate onto a nanoporous membrane with the nanoporous graphene sheet in contact with the nanoporous membrane; and
etching away the substrate;
chemically functionalizing the nanoporous graphene sheet to form a functionalized nanoporous article; and
layering two of the functionalized nanoporous articles together with the chemical functionalizations facing each other;
wherein the chemical functionalizations are crosslinked to each other.
