Rubrene (5,6,11,12-tetraphenylnaphthacene) is a red colored polycyclic aromatic hydrocarbon. It has the appearance of a red crystalline powder. Rubrene is used as a sensitiser in chemoluminescence. In lightsticks it is used to produce yellow light.

Rubrene is an organic semiconductor, used in OLEDs and OLED-based displays. Single-crystal transistors can be prepared using crystalline rubrene. Crystals of rubrene and other organic semiconductors are generally grown in a modified zone furnace on a temperature gradient, by a technique known as Physical Vapor Transport. This method was introduced in 1997 by R. A. Laudise, Christian Kloc "et al."

Rubrene holds the distinction of being the highest mobility organic semiconductor, with Podzorov "et al." recording room-temperature field-effect mobilities of ~30$cm^2/Vs$ along the crystallographic b-axis using a novel air-gap dielectric architecture. It has also been employed to demonstrate the Hall Effect in rubrene, cited (along with photoconductivity experiments) as evidence of diffusive, band-type transport in organic crystals.
