“…64,66,72,87,101 We determined various ET parameters, including V and , for porphyrin-fullerene systems from the CT absorption and emission for the first time. 64,66,72,87,101 Such CT absorption and emission were also reported for other fullerene-porphyrin-linked [102][103][104][105] and fullerene-phthalocyanine-linked 106 systems. Furthermore, the specific -interaction has been successfully used in dye-sensitized bulk heterojunction solar cells consisting of porphyrin and fullerene (vide infra).…”

Various porphyrin-fullerene-linked systems have been prepared to elucidate the intrinsic electron-transfer properties of fullerenes. Photodynamical studies on porphyrin-fullerene-linked systems showed that spherical fullerenes accelerated photoinduced electron transfer and charge-shift, but slowed down charge recombination, which is in sharp contrast with those of conventional planar acceptors such as quinones and imides. For the first time, it was shown that the unique electron-transfer properties result from the small reorganization energies of fullerenes arising from the delocalized system on the sphere together with the rigid structure. The small reorganization energies make it possible to produce a long-lived charge-separated state with a high quantum yield in donor-fullerene systems. The finding also will allow us to construct light energy conversion systems as well as artificial photosynthetic models. Highly efficient photoinduced energy and electron transfer were achieved on gold and ITO electrodes modified with self-assembled monolayers of the porphyrin-fullerene-linked systems. We also developed dye-sensitized bulk heterojunction solar cell possessing both characteristics of dye-sensitized and bulk heterojunction solar cells. These results showed the advantages of fullerenes as electron acceptors in artificial photosynthetic model, photonic molecular devices and machines, and organic molecular electronics including solar cells.

Porphyrins and fullerenes are spontaneously attracted to each other. This new supramolecular recognition element can be used to construct discrete host-guest complexes, as well as ordered arrays of interleaved porphyrins and fullerenes. The fullereneporphyrin interaction underlies successful chromatographic separations of fullerenes, and there are promising applications in the areas of porous framework solids and photovoltaic devices.

A donor (D)-acceptor (A) based system has been developed with the help of a newly synthesized Znporphyrin complex and C 60 fullerene. A series of spectroscopic methods, absorption spectroscopy (UVVis-NIR), powder X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) measurements, confirm the existence of a charge transfer based complex between Zn-porphyrin and C 60 fullerene. By using this D-A based system, circular disc-like nano objects have been generated. With the help of these nano objects, a diode has been fabricated. Current-voltage (I-V) and the capacitance-voltage (C-V) analyses of the diode were performed. The critical role of the Ag-C 60 -Zn-porphyrin and C 60 -Znporphyrin-SiO x interfaces are clearly understood from the I-V characteristics of the present device.Existence of a hysteresis loop in the C-V plot indicates that the device is indeed suitable for charge storage applications.
