| Outline of Final Research Achievements |
This project aims to create new compounds based on “superatoms” composed of a given-number of metal atoms. The main achievements were listed below.
(1) Gas phase reactions of coinage metal atomic anion or aluminum clusters with organic molecules yielded new products. We revealed that the thiolate protected Au clusters smaller than Au147(SR)60 exhibited icosahedral structure motif and discrete electronic structures. A variety of Au superatoms, such as Au8Pd(6e), Au8(6e), Au11(8e), Au11(10e), have been synthesized and their electronic structures, bond stiffness and optical properties.(2) Superatomic molecules made of cuboctahedral Au13 or Au147 units have been synthesized and the origin of the intense photo absorption in the near IR and IR regions were studied.
