| Outline of Final Research Achievements |
Size controlled synthesis of subnano ordered metal clusters was carried in the liquid phase. Poly(benzylether) dendrons were attached to the third generation of polyamine dendrimer by divergent-convergent method to afford core-shell type dendrimers. Increasing the generation of the dendrons afforded more rigid internal nanocavity which was suitable for formation of Pd4 clusters. Rh5 clusters could be prepared using the surface alkylated polyamine dendrimers. The ammonium cation within the dendrimer acted as the counter cation of the Rh cluster anion. Highly selective reduction of aromatic nitro groups under the water-gas shift reaction conditions.
