Fluorocarbene, Fluoroalkyl, and Fluoride Complexes of First-Row Transition Metals
… reactivity. The synthesis of bis(perfluoroalkyl) complexes serve as precursors for preparation of perfluoroalkyl cobalt(III) fluorocarbenes, which undergo migratory insertion reactions of the fluorocarbene into the perfluoroalkyl ligand. Using a similar synthetic approach, nickel(II) …

Understanding the nonaqueous partitioning of per- and poly-fluoroalkyl substances (PFAS)
Per- and polyfluoroalkyl substances (PFAS) are emerging contaminants that have been extensively used as firefighting agents and released to the environment, accumulating in waters, soils, and the atmosphere. PFAS are known to bioaccumulate, leading to adverse health outcomes. Therefore, …

Removal of Per- and Poly-fluoroalkyl Substances (PFAS) from Water: A Computational Approach
Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic compounds widely detected in the environment due to the exceptional stability of the carbon–fluorine bond, posing significant risks to human health and ecosystems. This dissertation develops a multiscale framework for PFAS …

Synthesis and biological evaluation of 11beta-substituted and 7alpha-substituted estradiol analogs for the study of estrogen responsive breast tumors
… substituted at the 11$\beta$-position with a fluoroalkyl or fluoroalkoxy substituent. These compounds bind to the estrogen receptor with high affinity, with the fluoroalkyl analogs being somewhat better binders than the fluoroalkoxy ones. All of these fluorine-substituted estrogens were …

A Radical Approach to Photochemical Transformations Using Earth-Abundant Metals
… of LMCT and other pathways. The introduction of fluoroalkyl groups to parent molecules is a powerful tool to modulate biological and physiological activities of these compounds through enhancement of lipophilicity, bioavailability and metabolic stability. One direct way to introduce these …

Synthesis of Well-Defined Multi-End Functionalized Polymers via Living Anionic Polymerization
… wide range of molecular weights, carrying 1 to 3 fluoroalkyl groups that have been prepared by end capping the living chain ends of polymers prepared via anionic polymerization reactions. The resulting polymers have a well-defined structure with interesting surface modifying properties. We have …

A geography of the disruptive effects of contaminated sites on residents’ mental health: The regulation of PFAS sites in NSW, Australia
… of sites contaminated by per- and poly-fluoroalkyl substances (PFAS) relates to the mental health and wellbeing of residents living with the contamination. This relationship was explored through thematic analysis of interviews with residents and government officials (n = 16), a …

A Showcase of Functional Fluorous Materials and Their Applications
… conjugated organic materials functionalized with fluoroalkyl chains and explores their applications in material chemistry. In Chapter 1, we begin with a brief introduction of incorporation of fluorine into materials and its effect on materials properties. An introduction to dynamically …

Functionalization of Metal Oxide Surfaces through Chemical Reactions and Physical Adsorption
… methyl-terminated and cyclic PDMS as well as bis-fluoroalkyl disiloxanes for the surface functionalization of mesoporous silica. FTIR and chemical analysis, as well as contact angle measurements and water adsorption confirmed the formation of high quality hydrophobic surfaces. An additional study …

A Gas Sensor for the Selective Detection of Volatile Organic Compounds
… adsorbents with amino, chloro, (n8) alkyl, fluoroalkyl, phenyl and chlorophenyl functionality. Analysis of BTEX vapours with the seven silica adsorbents indicated adsorption was physical (physisorption) and desorption was readily reversible between 25 and 100 °C. Adsorption was influenced by …

Interactions of Environmental Pollutants with Human Gut Bacteria
… PFNA belong to the chemical group of per-/poly-fluoroalkyl substances (PFAS) – the so called “forever chemicals”. PFAS are a major cause of environmental and health concern due to their toxicity, long-term persistence, and lack of an efficient way for their removal from the environment or the …
