We have synthsized new two dimensional nitrogen containing covalent organic framework (COF) materials with conductive backbones that may be ideal candidates for many electrochemical applications. The materials are "bottom up" synthesized rather than top down as in modifification of graphene or graphene oxide. We can produce materials with various sized ordered nanopores that can be functionalized with virtually any functional group. For electrochemical membrane applications we focus on lining the pores with charged carboxylate, quaternary nitrogens and sulfonate groups. Prelimary studies indicate that, depending on the dimension of the COF backbone, we can put as many as 6 to 12 carboxylate groups in each nanopore and have demonstrated selective ion conductivity to both size and charge with membranes fabricated with these materials.
