Iron Cytochrome C Nanohybrids – Supramolecular Electron Transfer to an Electron Accepting Fullerene

Abstract

Summary For the first time, intracomplex electron transfer reactions were tested in cytochrome c based nanohybrids (i.e., Fe(II)CytC and Fe(III)CytC), to which polyanionic C60 derivatives were electrostatically associated. Successful radical ion pair formation, namely, oxidized FeCytC and reduced C60, was detected when divalent Fe(II)CytC is used. The so formed Fe(III)CytC · C60 •− lives for 2.4 ± 0.5 μs.
