This PhD project at the University of York explores the fundamental photochemical behavior of β-diketones, focusing on how electrostatic perturbation via alkali metal complexation can disrupt their photochemical landscape. Keto-enol tautomerism is a central mechanism in organic chemistry, and recent research in the group has shown that alkali metal cations can reverse the energy ordering of keto-enol tautomers in molecules like avobenzone, leading to novel photochemical properties. The project aims to systematically study a series of β-diketone complexes using advanced analytical techniques, including IR-laser and UV-laser interfaced mass spectrometry, to measure spectra and investigate tautomer-dependent photochemistry. Computational chemistry using ab initio methods will support the interpretation of experimental data.

The research will also address the broader implications of electrostatic tuning for analytical chemistry, particularly in mass spectrometry, where metal ion complexes may affect molecular assignments. The project offers comprehensive training in mass spectrometry, laser spectroscopy, and computational chemistry, with additional opportunities to develop skills in data science, Python programming, and machine learning. Students are encouraged to participate in conferences, international collaborations, and publish in high-profile journals.

The Department of Chemistry at York is committed to equality and diversity, holding an Athena SWAN Gold Award and participating in initiatives to widen participation in doctoral study. Funding is available through the Department, EPSRC, or Chemistry Wild Fund, covering tuition, stipend, and research costs for 3 or 3.5 years, depending on the funding source. Applicants should have or expect to achieve at least a UK upper second class degree in Chemistry or a related subject, and meet English language requirements if applicable.

The application process includes online submission, possible supervisor contact, and panel interviews for shortlisted candidates. The project is ideal for candidates interested in experimental and computational approaches to physical organic chemistry and instrumental development.
