Organometallic porous materials can be utilized as highly accurate, effective, and low-energy agents in gas separation. Metal centers bind selectively to gas molecules to fill the pores in the material. This project tests the ability of chromium metal-ligand clusters that are coordinated to one another through hydrogen-bonding networks — as opposed to traditional organic linkages — to create a long-range, high-density, highly selective, porous material. Multiple ditopic ligands have been synthesized using standard organic synthetic procedures, and their structure analyzed with 1H NMR. These ligands were reacted directly with chromium metal compounds, chromium (III) chloride hexahydrate and chromous acetate, to create metal-organic complexes. Analysis through UV-Visible and Infrared spectroscopy indicated successful synthesis of the desired chromium complexes. Preliminary results indicate that the use of bidentate carboxylate ligands with nitrogen-rich substituents is the most effective way to generate a stable metal cluster with a strong hydrogen-bonding ability to ensure long-range rigidity. A ligand synthesized from dicyandiamide and 4-cyano benzoic acid has proven to form stable chromium clusters in both inert and atmospheric conditions. Current research is focused on forming long-range hydrogen-bonding networks with the aforementioned clusters to create a porous material. When this material is synthesized, the metal sites remain bound to one solvent molecule, which is then removed through vacuum to open a highly selective binding site. It is expected that the low oxidation state of the metal center will lend itself to be readily oxidized by gas molecules such as O2; but, critically, will not react with reducing agents such as N2. This highly selective nature of the binding site promises successful use of the material to replace thermal gas separation processes and reduce energy consumption nationwide.
