| Outline of Final Research Achievements |
Ligand-protected metal clusters, whose diameter is ~nm has been attracted as building block of functionalized future nanomaterials, because they have size-dependent properties like photoluminescence or catalytic activity, which are not shown in bulk metal. This work demonstrated the development of technique for ultra-high-resolution separation of mixture containing various composition of ligand-protected clusters obtained in the synthesis process, by using high-performance liquid chromatography. By applying our separation method, the mixture of gold-silver alloy cluster, whose some gold atoms in gold cluster were replaced with silver atoms, were separated into each clusters with individual composition for the first time. In addition, it has been revealed that our method can separate the isomers, whose doping-site of silver atoms are different.
