| Outline of Final Research Achievements |
On the basis of transition-metal catalyzed coupling reaction, we have prepared a tetrabenzoperipentacene and a fused pyrene trimer. These structures are considered as nano-graphene models. Oxidative ring closure reaction of a tetranaphthylpyrene derivative allowed synthesis of the all-56-carbon conjugative tetrabenzoperipentacene. From the X-ray structure, it is revealed that three molecules make a triple-layered cluster via π-stacking manner in which each layer rotates by 120°, considered as a petit β-graphite.
