Synthesis and Characterization of C70-Corrole-A New Electron Transfer Dyad

A new electron transfer dyad, covalently linked C-70-corrole, was prepared via C-70 and 10-(4-Formylaryl)-5,15-bis(pentafluorophenyl). The structures and the properties of the new material were investigated by HPLC, MALDI-TOF-MS, UV-Vis-NIR spectroscopy, NMR, fluorescence analysis and CV/DPV. The free-energy of C-70-corrole calculated by employing the redox potentials and singlet excited-state energy suggested the possibility of electron transfer from the excited singlet state of corrole to the fullerene entity, which agreed with the results of the theoretical calculation.
