Supramolecular Photoluminescence Paper Published in JACS Au

Congratulations to Jacob on the acceptance of our collaborative paper in JACS Au, developed together with Prof Guanglu Wu and colleagues at Jilin University. The paper shows how cucurbit[8]uril-confined chromophore dimers can be used to control dual emission by progressively restricting molecular motion, switching the dominant emission from short- to long-wavelength states while strongly enhancing fluorescence quantum yield. These results establish controlled supramolecular dynamics as a powerful strategy for designing programmable optoelectronic materials.

Welcome to Sanjoy Patra

Welcome to Sanjoy Patra who has recently joined the Oliver group as part of the EPSRC-NSF Quantum Information Science grant, investigating spin-correlation and coherences. Sanjoy completed his MSc-PhD at the Indian Institute of Science, Bangalore, under the supervision of Dr. Vivek Tiwari, where he focused on the development and optimisation of polarisation-controlled multidimensional electronic spectroscopy to study singlet fission and symmetry-breaking charge separation in molecular dyads. In his MSc, he also developed theoretical frameworks for formulating effective normal modes to describe vibronic effects in molecular dyads.

Transient absorption using a multi-octave continuum probe paper accepted for publication in JPCL

A new paper detailing the development and first application of a multi-octave continuum probe in ultrafast liquid-phase transient absorption spectroscopy has been accepted for publication in the Journal of Physical Chemistry Letters. The paper is available to read here. This work was undertaken at the University of Southern California in Steve Bradforth’s lab, and is the first paper to emerge from Tom’s sabbatical as part of a Leverhulme International Fellowship.

Dr Alex Stuart Joins the Group

Welcome to Dr Alex Stuart, who joins the Oliver group as a postdoctoral research fellow working on the BBSRC-funded sLoLa Circuits of Life grant. She previously worked as a postdoc at the University of Sydney with Prof. Girish Lakhwani, where she used optical spectroscopy to study the photophysics of organic semiconductors for optoelectronic applications. Prior to this Alex received her PhD from the University of Adelaide with A/Prof. Tak Kee and A/Prof David Huang, primarily on singlet fission and the photochemistry of polyacenes.

Alex was recently awarded the Cornforth Medal by the Royal Australian Chemical Society for her outstanding PhD thesis. The national prize is annually awarded in Australia “for a thesis on chemical research, recognising outstanding achievement in Chemistry and to promote chemical communication.”

£1.2M UK-US grant awarded to explore how quantum spin-entanglement dictates photochemical reaction yields

£1.2M has been awarded to the Oliver group and US collaborator Prof Stephen Bradforth (University of Southern California) for a collaborative 3-year project entitled Quantum Coherence and Correlations in Condensed Phase Photochemical Reaction Dynamics. The international collaborative project is UK-led, and funding for studies at the University of Bristol are supported by the Engineering and Physical Sciences Research Council, the US side is funded by the National Science Foundation.

The Oliver and Bradforth groups will study how important light-driven reactions key to photocatalysis, protein damage and drug design have spin-selective product yields that cannot be explained within a conventional classical framework. The applications of quantum information science are rapidly expanding beyond quantum computing, but the ramifications for solution phase chemical reactions remain largely unexplored. New multidimensional ultrafast experimental techniques will be designed to read out the developing spin-state and its entanglement at much faster timescales than have hitherto been possible from magnetic resonance experiments – looking critically at chemical phenomena through a new lens. The innovative experiments will correlate spin with both electronic and vibrational degrees of freedom, exploiting recent cutting-edge developments in short-pulse broadband deep-ultraviolet laser sources. Their discoveries will reveal how the quantum mechanical state imprinted by light maps through into specific distributions of products crucially determining the overall outcome of photochemical reaction and potentially laying the foundations for new high-value chemical synthetic products.

Olivia Hawkins completes PhD

Congratulations to Olivia Hawkins for passing her PhD viva voce exam on 23rd July 2025. Her PhD examiners were Prof Vas Stavros (Birmingham) and Prof Andrew Orr-Ewing (Bristol). Her PhD thesis entitled “Ultrafast Dynamics of 1,6-Diphenyl-1,3,5-Hexatriene in Complex Environments” used an arsenal of different experimental techniques to probe how the excited state photochemical dynamics of a model short-chain polyene and important bioimaging dye, DPH, are strongly influenced by their environment- in liquids or inside polypeptide barrels.

Boostcrop team awarded 2025 RSC Faraday Horizon Prize

The EU FET Open Boostcrop consortium, led by Prof Vas Stavros (University of Birmingham) were awarded a Faraday Horizon Prize by the Royal Society of Chemistry (RSC) for “boosting crop growth using natural product and synthesis enabled solar harvesting.” RSC Faraday Horizon Prizes recognise significant recent novel discoveries or advances made in the area of physical chemistry by groups or teams.

The Boostcrop team was comprised of 6 EU and 2 UK institutions spanning academia (chemistry/biology) and industry (synthesis/agriculture), including Bristol colleagues Kerry Franklin and Chris Groves from Biological Sciences. Daniel Polak (former post-doc in the Oliver group now at Leicester), Mike Ashfold (Emeritus Professor) and Tom were all members of the Boostcrop team, and share part of the 2025 Faraday Horizon prize.
