Porphyrinic coordination lattices with fluoropillars

The combined use of porphyrins and fluorides to fabricate pillared coordination sheets is presented. Multiple features, such as coordinatively unsaturated metal sites, an optimal pore space, and a fluoride-decorated internal surface, make the new materials ideal adsorbents with high capacity and affinity for carbon dioxide. In addition, the new materials are shown to be suitable single-source precursors to afford fluorine-doped graphene analogues for application in oxygen reduction reaction electrodes.
