Development and Testing of Fluorous Metal-Organic Frameworks (FMOFs) for Photoluminescent Sensing and Water Purification ApplicationsFripp, Jacob Linley 05 1900 (has links)
In this work, fluorous metal organic framework 1 (FMOF-1) and its isomorphic structures are investigated for both sensing and filtration applications. In chapter 2 both FMOF-1 and its acetone derivative, aFMOF-1, are shown to exhibit an unusual photoluminescent behavior by having a "turn-on" emission when exposed to vacuum. This baroluminescence occurs at different rates depending on specific gas, allowing FMOF-1 and aFMOF-1 to not only act as vacuum gauges, but also potentially act as sensors for gas identification. Chapter 3 focuses on chemical sensing properties (chemosensing) of the newly discovered second methanol derivative of FMOF-1, mFMOF-2. mFMOF-2 has been shown to be air and water stable, however exposure to volatile organic compounds (VOCs) will cause quenching or shifts in emission. Finally, chapter 4 investigates the ability of combining MOFs with more traditional sorbents to investigate the possibility of a hybrid material that takes advantage of both materials. MOFs have long been investigated for their filtration properties, however the high cost of synthesis of MOFs compared to the cost-efficient common filters hamstrings their real-world implementations. Combining a small percentage of FMOF-1 with activated carbon is seen to improve the filtration efficiency and to increase the hydrophobic properties. This hybrid filtration material avoids the problems associated with the cost of synthetic filtration materials since only 0.1% mass additive is shown to yield significantly improved results.
