NAPHTHACENE Usage And Synthesis

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 a lso 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.

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.
