Chemical Properties
orange powder
Uses
p-Type organic conductor and OLED dopant. Sublimed grade for organic electronic device applications.
Uses
Naphthacene is a polycyclic aromatic hydrocarbon. Naphthacene is often used as a molecular organic semiconductor in organic field-effect transistors and organic light-emitting diodes. Naphthacene is also used in various applications involving the enhancement of photocurrent.
Definition
ChEBI: An acene that consists of four ortho-fused benzene rings in a rectilinear arrangement.
General Description
Benz[
b]anthracene is an ethylnylated acene that is a conducting polymer, which can be used as a donor material. It has a high photoluminescence and quantum yield that makes it a promising candidate in the development of single crystal electronic material.
Hazard
Explodes when shocked, reacts with oxidizing materials.
Purification Methods
Naphthacene crystallises in orange needles from EtOH, *C6H6 or toluene. Dissolve it in sodium-dried *benzene and pass it through a column of alumina. The eluent is evaporated under vacuum, and the chromatography is repeated using fresh *benzene. Finally, the naphthacene is sublimed in vacuo at 186o.
