Pentacene consists of five linearly fused conjugated aromatic rings. This, combined with its favorable crystal structure, has made it the first organic molecule to be widely explored for the development of electronic devices. Specifically, pentacene has shown promise as a semiconductor in thin-film transistors and field-effect transistors. In the presence of air and visible or UV light, pentacene crystals change color from purple to green, the result of photooxidation of the central aromatic ring. Its synthesis was first reported in 1929.
