Tiny porphyrin tubes may lead to new nanodevices

Abstract:
Sunlight splitting water molecules to produce hydrogen using devices too small to be seen in a standard microscope. Thatís a goal of a research team from the National Nuclear Security Administrationís Sandia National Laboratories. The research has captured the interest of chemists around the world pursuing methods of producing hydrogen from water.

Porphyrin nanotubes are made entirely of oppositely charged porphyrin molecules that self-assemble in water at room temperature. The more well-known carbon nanotubes are formed at high temperatures and have covalent bonds between carbon atoms. Porphyrin nanotubes lack the high mechanical strength of the carbon tubes but possess a wider range of optical and electronic properties that can be exploited in making nanodevices.
