Abstract:
The use of N-heterocyclic carbenes to modify homogeneous metal catalysts is widespread since the high metal–NHC bond strength renders high oxidative and chemical stability to the resulting metal complexes. The use of NHCs to modify metal surfaces has received considerably less attention. We will describe the modification of planar metallic surfaces with NHCs. The nature of the surface overlayer is strongly dependent on the nature of the NHC. Similarly, NHCs are useful new ligands for the stabilization of metal clusters, with again the structure of the cluster being strongly influenced by the nature of the NHC.

Dr. Crudden has made significant impact on diverse areas of science. She described one of the first cross-coupling reactions with chiral, enantiopure molecules that has made considerable impact on the preparation of pharmaceutical compounds. More recently, she has demonstrated the strength and versatility of N-heterocyclic carbene ligands in materials science, showing these ligands to be viable and versatile alternatives to thiolates as ligands for planar metal surfaces, nanoparticles and nanoclusters. This work has been called "game changing", "elegant" and "the new gold standard" by experts in the field.
