Photoinduced electron transfer processes of two newly synthesized tetrads with a triphenylamine (TPA) as central building block, to which bisfullerenes (C60) and bisferrocenes (Fc) are covalently connected, have been studied. One of them has a TPA linked with one C60 moiety and two ferrocene moieties C60–TPA–(Fc) 2 and another tetrad has a TPA linked with two C60 moieties and one ferrocene unit (C60) 2–TPA–Fc. The ...
