Abstract

The project has as a goal the synthesis of nanostructured metal organic frameworks (MOFs) for carbon dioxide capture, constituted of alternated layers of aromatic diimides and zirconium phosphonate. The materials will be prepared in the form of either crystalline solids or layer-by-layer thin films. The precursor imides will be synthesized through the reaction of pyromellitic dianhydride with 2-aminoethylphosphonic. Porosity will be induced in the MOFs by means of addition of small phosphonate-substituted molecules. The resulting materials will be characterized by a variety of techniques, such as x-ray scattering, nitrogen adsorption isotherms and different spectroscopic methods. The capacity of the materials to bind CO2 will be tested.
