After preparing the precursors, several different reaction conditions were attempted, but the desired COFs proved elusive. The second class of materials was tetrathiafulvalene-based metal-organic frameworks (MOFs). These materials were constructed with tetrathiafulvalene tetrabenzoic acid and zinc, cobalt, and manganese nitrate to give helical structures with approximately cylindrical pores. This structure type has one close S-S contact of 3.8 Å which acts as a potential avenue for charge transfer. Gas sorption measurements suggest that the materials retain porosity upon evacuation.
