About the research project

Perfluoroalkyl substances are a group of potentially harmful molecules that have been widely used in firefighting foams, cookware, water resistant clothing, and food packaging. These compounds do not degrade readily, and have a tendency to bioaccumulate.Most of the general public has been exposed to PFAS, and concerningly, high concentrations of these molecules are being found in soil and water sources. PFAS exposure has been associated with a number of cancers, and been linked to low birth weight and diminished organ function. The established methods to identify PFAS are costly and time consuming, requiring large laboratory instrumentation for detection and quantification, and taking days to weeks to obtain results. The work of the Kilah group has identified molecular structures that are able to instantly change colour in the presence of PFAS pollutants, allowing for the rapid and user friendly detection of PFAS at real world concentrations in soil and water. The detection of these pollutants is facilitated by supramolecular interactions between our coloured hosts and the perfluorinated guests. In this project, the candidate will syntheses supramolecular structures that incorporate recognition groups to further explore the detection of PFAS.

The project will commence with the synthesis of these new compounds using established organic and inorganic synthesis techniques. The newly prepared and isolated molecules will be characterised by Nuclear Magnetic Resonance (NMR) spectroscopy, UV-Visible Spectroscopy, Mass Spectrometry, and X-ray crystallography. These molecules will then be applied to the challenge of binding and responding to a range of PFAS pollutants under a number of real world conditions. These investigations will use UV/Visible spectrophotometry and fluorescence spectroscopy to investigate the strength of the binding interactions between the prepared compounds and PFAS.
