Greener processes based on coordination chemistry;
ligand design for surface engineering and metal recovery
Coordination chemistry has had an impact on many areas of science,
ranging from photophysics to biology, and underpins the development
many industrial products and processes. Much of the work in our group
involves the design of ligands which bind very strongly and selectively
to metal ions or metal surfaces. Functionalizing the ligands then allows
us to tailor the properties of the complexes and use these in metal-recovery,
surface engineering, metal deposition and in the development of new
Simple oxime ligands achieve concentration and separation of copper
in solvent extraction processes which now account for nearly a third
of the world’s copper production.5 We have recently
developed systems which can extract both Cu2+ and its counter
Phosphonates bind strongly to aluminium oxide surfaces and protect
the Al flakes used in metallic paints on cars, preventing the formation
of Al(OH)3 which has a deleterious effect on the appearance
of the reflective surface.1
