Research is directed towards using the properties of the carbon―fluorine bond in organometallic chemistry and for highly repellant surfaces.
- Organometallic Chemistry
- The extreme strength and the electronic and steric properties of the C―F bond are used to confer useful properties on organometallic complexes, in particular catalytic activity.
- C―F bond fission is used to synthesize organometallic complexes, not accessible by other routes.
- Superhydrophobic Surfaces
- The extreme water repellancy of perfluoroalkyl groups is used to confer superhydrophobicity on metal surfaces. The work has been highlighted by Nature and Scientific American. The simple fabrication technique allows a range of unusual phenomena to be investigated, such as the Cheerios Effect and 'super-buoyancy', which allows boats to be constructed of metal mesh, and has potential industrial importance.
