Research interests

My research group is currently working in the following areas:

1. Symmetrical polynucleating macrocycles - towards soluble stable 3d-4f Single Molecule Magnets
2. Heterocycle-containing ligands
3. Spin crossover complexes - towards nanoswitches and memory devices (Moessbauer spectroscopy 4-300 K in house, in collaboration with Dr Guy Jameson)
4. Attachment of magnetically interesting complexes to nanoparticles (in collaboration with Dr Carla Meledandri)
5. Self-assembly of communicating arrays of transition metal ions - grids vs side-by-side complexes
6. Thiolate-containing ligands - models for hydrogenases (H₂ = 2H⁺ + 2e^-)
7. The oxygen evolving complex of green plants (2H₂O = O₂ + 4H⁺ + 4e^-), in collaboration with Dr J. Eaton-Rye (Biochemistry)
8. Lanthanide cages as a new generation of luminescent ‘probes’, in collaboration with Drs Jean Fleming (Anatomy and Structural Biology) and Sally McCormick (Biochemistry).
