    • The various light-absorption cross sections toward nanorods are possible considering the nanorod orientation on film (Figure 9B). On the other hand, the exciten diffusion length of organic dyes such as porphyrins is generally limited (ca. several nm). Considering these points and quenching properties of time-resolved measurements (fluorescence lifetimes and transient absorption), we can propose that light-absorbed D/A interfacial, layers contribute mainly to the immediate charge-separation process. See the reference paper for exciton diffusion of porphyrins:Huijser, A.; Savenije, T. L; Meskers, S. C. L; Vermeulen, M. J. W.; Siebbeles, L. D. A. J. Am. Chem. Soc. 2008, 130, 12496.

    • On the basis of the discussion in ref 46, the broad photoresponse in the 600-700 nm region may contribute to charge separation via the excited state of fullerene assemblies.
