Electron-transfer reaction of the newly synthesized light harvesting pentad composed of silicon phthalocyanine (SiPc) that is connected with two fullerene C60 and two azobenzene units to form SiPc-(azobenzene) 2-(C60)2 pentad has been studied by laser flash photolysis and other complementary techniques. This combination between SiPc, azobenzene and C60 in the examined SiPc-(azobenzene) 2-(C60)2 pentad leads to strong light absorption over the whole visible spectrum. Photoexcitation of the pentad results in rapid formation of the charge-separated state by photoinduced electron transfer from the singlet-excited state of the SiPc moiety to the C60 moiety. The charge-separated state has a lifetime of 2.50 ns in benzonitrile.
