Ferrocene-appended Subporphyrins
meso-Tris(4-ferrocenylphenyl)subporphyrin 1 and meso-triferrocenylsubporphyrin 2 were prepared. The structure of 2 was confirmed by X-ray analysis. Both molecules exhibit substantially red-shifted absorption spectra and almost complete fluorescence quenching, due to the influence of the electron-donating ferrocene substituents. Subporphyrin 1 exhibits a nonsplit oxidation wave for the oxidation of the ferrocene moieties, while subporphyrin 2 exhibits a split reversible oxidation wave with Delta E = 168 mV to indicate effective electronic communication.
