Large-scale chemical synthesis method for targeted nanoclusters should be established to obtain large amount of nanoclusters. The selective synthesis and efficient isolation of the targeted nanoclusters are very important, because the functionalites strongly depend on the cluster size and chemical composition. In addition, we will explore to fabricate spatially uniform solid surfaces in macro-scale by self-organization of organic monolayers and/or matrices to use them as the supporting materials, where and the nanoclusters can be immobilized in identical environments. In this project, we investigate two major nanoclusters for the building blocks of the advanced cluster-based nanomaterials; one is (A) metal atom-encapsulated silicon cage clusters and the other is (B) organometallic sandwich clusters. Our previous gas-phase studies have shown that these nanoclusters exhibit electromagnetic properties with novel geometric structures, and thus the two can be regarded as functional units to apply the innovative nanodevices.
