Abstract

Energy funnels: A large dendritic zinc porphyrin heptamer (7P _Zn) in a C₆₀-terminated electron-transfer relay system 7P_Zn-C₆₀ (see picture) not only harvests visible light for the electron transfer to the C₆₀ terminus, but also retards the back-electron-transfer process, thus resulting in a longer lifetime of the charge-separated state (7P_Zn^.+-C₆₀ ^.-).
