Dendrimers or dendrons having chromophore at the core or focal point were synthesized, and effects of dendritic substituent on photofunctionality were investigated. We found photoisomerization from ally! alcohol to ketone by the use of dendrimer disulfide as catalyst. Various photooxygenation reactions proceeded by the use of Cd10S16 molecular cluster dendrimer or fullerodendron as photosensitizer of singlet oxygen. Photoinduced charge separation of fullerodendrimers take place with high quantum efficiency in aqueous solution. In the presence of viologen dication and a sacrificial donor, the persistent viologen radical cation was generated. This electron pooling efficiency was obviously enhanced by the use of single-walled carbon nanotube/fullerodendron supramolecular system.
