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.

In this review, we report the recent advances in the construction of composite molecular nanoarchitectures of porphyrins and nanoscale carbon materials such carbon nanotubes (CNT), graphenes and polycyclic aromatic hydrocarbons (PAH) for photoinduced electron transfer and light energy conversion. First, we state novel single-wall carbon nanotubes (SWCNT)-driven aggregation of protonated porphyrins to produce supramolecular assemblies in the form of macroscopic bundles. Then, photoinduced electron transfer in self-assembled single-walled carbon nanotube (SWCNT)/zinc porphyrin (ZnP) hybrids utilizing (7,6)- and (6,5)-enriched SWCNTs having different band gaps is reported. Further, we discuss the structural and photoelectrochemical properties of porphyrin-based molecular assemblies of other carbon materials such as stacked-cup carbon nanotubes (SCCNT), carbon nanohorns (CNH) and graphenes. Finally, novel supramolecular patterning formation composed of triphenylene core-centered porphyrin hexamers for electronics is discussed.
