Tetracene, also called naphthacene, benz[b]anthracene and 2,3-benzanthracene, is a polycyclic aromatic hydrocarbon. It has the appearance of a pale orange powder.
It is a molecular organic semiconductor, used in OFETs and OLEDs. In May 2007, researchers from two Japanese universities, Tohoku University in Sendai, and Osaka University, have reported an ambipolar light-emitting transistor made of a tetracene single crystal Ambipolar means that the electric charge is transported by both, positively charged molecular cations and negatively charged molecular anions. Tetracene can be also used as a gain medium in dye lasers. Jan Hendrik Schön during his time at Bell Labs (1997-2002) claimed to have developed an electrically pumped laser based on tetracene. However his results could not be reproduced and it is considered scientific fraud.
