Tetracene, also called naphthacene, is a polycyclic aromatic hydrocarbon. It has the appearance of a pale orange powder. Tetracene is the four-ringed member of the series of acenes, the previous one being anthracene (tricene) and the next one being pentacene.

Tetracene is a molecular organic semiconductor, used in organic field-effect transistors (OFETs) and organic light-emitting diodes (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 single tetracene crystal.[1] Ambipolar means that the electric charge is transported by both, positively charged holes and negatively charged electrons. Tetracene can be also used as a gain medium in dye lasers as a sensitiser in chemoluminescence.

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 to be scientific fraud.[2]
