13. 10-12 Since the porphyrin bears bulky tert-butyl groups on the meta positions of the phenyl groups at the meso-positions, the clustering may be ascribed to the strong three-dimensional hydrophobic interactions between the fullerene units or the fullerene and the porphyrin units rather than the porphyrin units.
14. The difference in shape and the peak position between the two spectra may be due to the difference between the actual spectrum obtained in transmission mode in air and the real spectrum on the electrode under the photoelectrochemical conditions, where the dyads are in contact with the electrolyte solution.
15. The quantum yield of photocurrent generation in the present systems is estimated as ∼ 0.4%.
