This project is broadly centered in understanding the host-guest properties of coordination-driven self-assembled metal-organic materials (MOMs) such as discrete molecular metal-organic polyhedra (MOP) and polymeric metal-organic framework (MOF). The self-assembly of these materials has been widely studied due to their interesting properties including well-defined internal cavities, rigid structures, and modular syntheses. These properties enable their use in a variety of applications including light-harvesting, energy storage, catalysis, molecule sequestration, and gas storage. This work is specifically focused on (1) evaluating the capacity of metal-organic materials for pollution management, i.e. water purification, as well as gas storage and (2) designing composite materials wherein an organic polymer is embedded with these self-assembled MOMs. A suite of analytical techniques including spectroscopy, microscopy, diffractometry, calorimetry, and gravimetry are used in order to fully characterize our MOMs and composite materials. Initial work demonstrated the host-guest chemistry of a Cobalt(II) MOF known as a "crystalline sponge" for its ability to encapsulate organic dyes in water. The insolubility and water-instability of most MOFs limit their application in water treatment technologies unlike MOPs which are stable and soluble in a range of solvents making them more processable as additives to mixed-matrix materials (MMMs). We then studied a group of MOPs as fillers for MMMs with a polyvinylidine fluoride (PVDF) polymer phase and contrasted them against MMM containing MOF-5. We demonstrated the formation of thin, flexible, and homogeneous MMMs when a given MOP was soluble in the precursor solutions. With our ability to incorporate MOPs into polymer to make membranes, we started to investigate the self-assembly of group 11 metallacycles for olefin/paraffin separation due to a precedent that silver metal ions can interact with ethylene and light olefins over related paraffins. We observed that the precipitation of Ag(I) and Au(I) hexagonal metallacycles upon assembly in chloroform/methanol mixtures resulted in high solid-state photo-stability. Finally, the anionic molecular cage, FeMOP, was demonstrated to encapsulate per- and polyfluoroalkyl substances (PFAS) in water. The key findings from these host-guest studies can be applied to future metal-organic materials design and modification for improved cage incorporation in mixed-matrix materials with optimized performance in gas separation and water purification.
