| Research Abstract |
In order to control the meso-architecture of self-assembled semiconducting materials, several new dendrimers have been synthesized. For instance, a fullerodendron having sugar moieties at the terminals, DBN-focal dendrons and their fullerene adducts, and a dendrimer having diphenyl diselenide at the core. Interestingly, fullerodendrons are self-assembled on the surface of single-walled carbon nanotubes(SWCNTs) to form the SWCNT/fullerodendron supramolecular nanocomposite that have nicely ordered photofunctional interface generating charge separated state via photoinduced electron transfer process. Furthermore, the supramolecular nanocomposite was covered by SiO_2 to produce the SWCNT/fullerodendron/SiO_2 coaxial nanohybrid that can be used for the photocatalyst for water splitting. It is notable that the quantum yield of H2 generation reaches to 31% upon visible light irradiation.
