Light Energy Conversion

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.

AbstractCarbon nanomaterials have unique physicochemical properties based solely on their small size, which makes them ideal for nano-oncology. While there have been tremendous advances in the current treatment of high-risk cancers, conventional treatment still causes harm to the surrounding healthy tissue. Carbon nanomaterials such as carbon nanotubes, carbon nanohorns, and graphenes have been increasingly used in the field of cancer photothermal therapy. Through surface functionalization, carbon nanomaterials can be specifically targeted to the tumorous tissue allowing for an increase in therapeutic potential. The unique photo-electron transfer features of carbon nanomaterials coupled with functional moieties, is proving useful for their use in the photothermolysis of cancer cells.
