Very high photocurrent generation is seen for an ordered supramolecular composite structure of C60 and porphyrin assembled on SnO2 electrodes. The simple substitution of methoxy groups at the meta positions of the meso-phenyl groups on the porphyrin ring leads to the ordered stacking arrangement shown in the figure, with separate electron and hole transport paths along the 1D porphyrin chains and 2D C60 sheets.
