This project will focus on the synthesis of porphyrin arrays with paramagnetic metal centres (e.g. Cu²⁺, Ag²⁺ or Gd³⁺) at precisely defined spatial positions and the investigation of long-range interactions between these cations by electron paramagnetic resonance (EPR) spectroscopy. The aim is to gain understanding of quantum interference.

Molecularly-made graphene nanoribbons allow combining efficient charge transport with spin properties, if they are functionalized with metals. Recently, we demonstrated that the spin states injected via organic radials have appealing quantum properties. Coordination with metals on the edges , instead of using organic radicals, would allow shaping their topological and quantum properties. This project aims to establish the coordination chemistry of molecular graphene nanoribbons, focusing on rare-earth compounds in particular, and characterize them by transport, optical spectroscopy, pulsed EPR spectroscopy and SQUID magnetometry.

This project will involve control of crystal structure and electron count in layered oxide chalcogenides and oxide pnictides in order to realise potential new thermoelectric materials with the almost contradictory properties of high thermopower, high electronic conductivity and low thermal conductivity. High and low temperature synthetic methods will be employed together with a wide range of physical and structural characterisation methods to establish structure-property relationships.

This project will combine state-of-the-art supramolecular / coordination complex design and synthesis with molecular film electronic and optical analysis. The aims are to (i) develop novel responsive, sensory films that incorporate inorganic coordination complexes as receptors for anionic species, with switchable functionality, and supported within electrode-mounted lipid membranes; and (ii) to explore how the capture of target anions such as peptides can be detected through ultra-sensitive optical or electronic sensing response.

The aim of this project is to synthesise compounds of the heavier main-group elements with unprecedented heteroatomic multiple bonds (e.g. Al=P). Preliminary work by the Goicoechea group has shown that such bonds are highly polarised and can be used for the activation of small molecule substrates such as H2 and CO2. Our goal is to build on these results with the aim of developing compounds that may ultimately be able to act as catalysts in a number of chemical processes including hydrogenation and hydroamination reactions.

Prussian blue analogues are one of the most important new families of cathode materials for Na and K-ion batteries: they are cheap and chemically versatile, and have both high charge capacities and long cycle lives. Their solid-state structures are characterised by complex disordered networks of vacancies, and this project is concerned with developing synthetic control over these networks to optimise cathode performance.

This project is concerned with novel synthesis, testing, and characterization of transition metal nitride and sulphide nanostructures as new catalysts for green NH₃ production from H₂ and N₂ at mild conditions, i.e., room temperature, under controlled ultrasonic cavitation for fertilizer and use in energy. Rational synthesis using various solid-state synthetic techniques including MOCVD to establish the structures and surfaces for optimal catalysis will be combined with advance material characterization including diffraction, electron microscopy, and computation (to guide the synthesis).

The project unites methods for synthesis of selectively isotope-labelled small molecules (Vincent group) with incorporation of these labels into large proteins for NMR structure determination (Baldwin group). We use biocatalytic approaches to synthesise labelled amino acids and other biomolecules from the cheapest 13C, 15N and 2H building blocks. Target proteins are then produced by fermentation of E. coli on isotopically labelled pre-cursors, for study by advanced NMR methods. The project is expected to lead to new, economical synthetic routes for labelled biomolecules, thus providing valuable resources for drug docking studies as well as structural biology more generally.
