Outline of Final Research Achievements

In this study, "organic-inorganic hybrid dendrimers with a functional nano-core" were designed and synthesized to induce synergistic functions derived from dynamic changes in the shape of the hybrid dendrimers, which are derived from the dynamics of the dendron on the surface of the nanoparticles. Specifically, the application to magnetic nanoparticles, gold nanoparticles and quantum dots was investigated. The results showed that, for magnetic particles, magnetic induction heating can be used to control the nano-structure at low temperatures, and change in the magnetic properties derived from the structure were successfully observed. In the application to gold nanoparticles and quantum dots, changes in nanoparticle functionality based on strong interactions with oligothiophene dendrons were seen on the nanoparticle surface.
