Outline of Final Research Achievements

In this work, we aimed to establish the new precise separation techniques for alloy clusters with different foreign atoms by high-performance liquid chromatography (HPLC). As a result, we have succeeded in separating each thiolate protected gold-silver alloy clusters by using appropriate column and separation program. The separation of each core size of gold clusters and each coordination isomer of alloy clusters have also be achieved via this technique. We could reveal the effects of heteroatom doping, the difference of core size, the combination of ligands against gold clusters and gold-silver alloy clusters throughout these types of works. We believe that the techniques and knowledge gained in these work would contribute to the creation of new clusters with the desired functions and associated functional nanomaterials.
