We have newly constructed supramolecular photovoltaic cells using inclusion complexes of lithium-ion-encapsulated [60]fullerene (Li+@C60) and cyclic porphyrin dimers (M-CPDPy, M = H4 and Ni2). First, supramolecular inclusion complexes of LiC60 and M-CPDPy were prepared in MeCN/PhCN (3/1, v/v) by rapid injection method. The molecular aggregates with spherical nanoparticles demonstrated a broad absorption property in the visible region. The macroscopic structures were also estimated to be ca. 200 nm in diameter by transmission electron microscope (TEM) and dynamic light scattering (DLS) measurements. The photoelectrochemical solar cells composed of these assemblies on nanostructured SnO2 electrode were fabricated by electrophoretic deposition method. The photoelectrochemical behavior of the nanostructured SnO2 film of supramolecular nanoassemblies of Li+C60 and M-CPDPy is significantly higher than those of the single component films (Li+C60 or M-CPDPy) and supramolecular inclusion complexes of pristine C60 and M-CPDPy.
