Outline of Final Research Achievements

With the Kakenhi funds, we have made significant progress on the synthesis and characterization of novel gold nanoclusters bearing phosphine and N-Heterocyclic carbenes (NHC) ligands. In addition, we have made strides to understanding their properties in terms of stability and catalytic reactivity. These results are broken down by cluster type. By tuning the method of synthesis and nature of the NHC, we have prepared new NHC-based gold clusters.

Academic Significance and Societal Importance of the Research Achievements

The development of NHC gold clusters will open up previously unknown possibilities in catalysis. Since the NHC not only forms a stable bond to the cluster, but also stabilizes the cluster itself, we will be able to perform the surgical removal of specific ligands without cluster collapse.
