Porphyrin Phthalocyanine

Photoinduced electron transfer in supramolecules composed of porphyrin/phthalocyanine and nanocarbon materials such as fullerenes, single-walled carbon nanotubes, and single-walled carbon nanohorns have been reviewed. With the aid of highly efficient visible-light harvesting porphyrin/phthalocyanine, the photosensitized electron transfer takes place from the photoexcited porphyrin/phthalocyanine to fullerene, which acts as a strong electron acceptor. In the case of nanocarbon materials such as single-walled carbon nanotubes and nanohorns, they may act as electron-trapping sites. From the holes and electrons generated on porphyrin/phthalocyanine-nanocarbons, electron pooling takes place at the strong and stable electron trapper (viologen dication) in solution.

We designed and synthesized SWNT quantum defects, the band gaps of which can be tuned by thermal treatment. Theoretical calculations suggest that the change in the PL spectra can be explained by isomerization from kinetic to thermodynamic products.
