Metal Triazolites

Tech ID: 30078 / UC Case 2011-250-0


UCLA researchers in the Department of Chemistry and Biochemistry have developed a novel metal-organic framework (MOF) using triazole ligands that allows for facile modification with a variety of metals, which has unique gas separation and adsorption properties.


Previous MOFs with advantageous porosity and stability have been synthesized, but only with a few types of organic building units. Metal-organic frameworks with alternative linker functionalities have not been fully realized. Likewise, conductive MOFs are relatively unexplored, despite great interest in using multifunctional material with high surface area and high electrical conductivity.


UCLA researchers have developed a unique synthetic approach to develop a new class of MOF materials. This method uses triazole and triazole derivative ligands, which can be easily modified via click chemistry, with several metal atoms, leading to a diverse set of MOFs. Six metal-triazole (METs) with varying divalent metals (Mg, Mn, Fe, Co, Cu, and Zn) have been synthesized (MET-1 to MET-6). Ultimately, this synthetic method can be used to tune the gas sorption properties and the topologies of the MET depending on the application at hand by varying the functionality of the triazole and the metal atom, respectively. These materials have been shown to have permanent porosity, stability in air, high thermal stability, and surface area that is comparable to zeolites and other MOF materials. Interestingly, MET-3 has been discovered to be electrically conductive, with a conductivity of 0.77 x 10‑4 S/cm.
