Multistep electron transfer systems based on silicon phthalocyanine, [60]fullerene and trinitrofluorenone

The synthesis and photodynamics in the absence and in the presence of Mg(2+) ions of a novel TNF-C(60)-SiPc-C(60)-TNF pentad are reported. The redox gradient approach allows to obtain a long-lived CS state of 160 ns and 200 mu s in the absence and in the presence of Mg(2+) ions, respectively.
