Metal-Organic Frameworks (MOFs) are materials that contain metal centers coordinated by organic molecules that form an extended, porous lattice. These MOFs are of interest in the field of sensing for their unique properties such as high stability, high surface area, high crystallinity, and ability to perform small molecule exchange. Luminescent metal-organic frameworks (LMOFs) are of specific interest since they contain the potential to detect volatile organic compounds via adsorption into the porous framework. 1 Luminescent properties can be imparted to MOFs in several ways. Previous projects focused on the inclusion of the luminescent osmium complex Os(dcphen)(CO)2 (Cl)2 (dcphen = 1,10-phenanthroline-4,7-dicarboxylic acid) into the lattice of zinc-based MOFs. These systems exhibited luminescence quenching when exposed to alcohols. However, zinc MOFs possess unique challenges when applied to water-based systems since they readily decompose in the presence of water which limits the potential for aqueous sensing. The goal of this project is to develop a LMOF that is stable in aqueous environments. MOFs composed of zirconium carboxylates exhibit fascinating properties such as high thermal stability and superior chemical resistance towards several solvents due to strong Zr-O bonds and high coordination number between the Zr clusters and organic ligands. The methodology in which these zirconium LMOFs are synthesized and the photophysical properties of the LMOFs in the presence of polar and nonpolar guest molecules will be detailed. The zirconium-based LMOFs proved to be stable in aqueous environments and will be further studied for sensing of analytes in the presence of water.
