Outline of Final Research Achievements |
Cyclodextrin-based metal-organic Frameworks (CD-MOF) are porous nanopore crystals with regularly arranged pores. CD-MOF can introduce functional molecules into the nanopores by adsorption or co-crystallization methods. In this study, we prepared CD-MOF including organic ligands that inhibit the aggregation of gold nanoclusters. Gold nanoclusters were synthesized using this as a template. The obtained gold nanoclusters were found to be extremely small, highly uniform in size, and exhibit optical properties.

Academic Significance and Societal Importance of the Research Achievements |
金属ナノクラスターは触媒やバイオセンサーなどの工学系から医薬系といった広い分野で応用が期待されている。しかし、金属ナノクラスターのサイズを合成時に制御することは容易ではなく、均一サイズの金属ナノクラスターの合成方法の確立が望まれる。本研究では、CD-MOFのナノ孔を用いて、均一サイズの極めて微小な金ナノクラスターの合成方法を開発した。
