| Outline of Final Research Achievements |
In this work, we aimed to creation of novel stable and functionalized nanomaterials by using magic numbered gold clusters as basic materials. As a result, we have succeeded in synthesizing thiolate protected novel trimetallic (gold, palladium, silver or copper) clusters and tetrametallic (gold, palladium, silver and copper) clusters. In order to investigate the substitutional effects of heteroatom, ligand-exchange reaction rates were explored. The results showed that incorporating silver and copper atoms enhanced the ligand-exchange reactivity of the clusters. Furthermore we could also change the properties of clusters by controlling the interfacial structure by substituting thiolate with tellurolate. Finally, the substituted site of tellurolate was revealed by X-ray crystallography.
