Zipping up carbon

Researchers at Nagoya University, in Japan, have developed a quick and easy way to make so-called nanographenes in a controlled manner. Their approach might open up applications of the much-hyped materials to allow novel optoelectronic devices for organic electroluminescent displays and solar cells to become reality. Nanographenes, are one-dimensional nanometer-wide strips of graphene. Their properties largely depend on their width, length and edge structures and so taking control of their synthesis is important to making viable devices from these materials.
