Pentacene Chemical Properties,Usage,Production

Applications

Pentacene, an acene with flat-like molecules made of five linearly-fused benzene rings, has been extensively studied as a p-type semiconductor in organic field-effect transistors. It is known to exhibit large carrier mobilities of about 1 cm2 /V s within the plane parallel to the substrate.
Due to its large carrier mobilities, pentacene has also been used with C60 in heterojunction solar cells with a power conversion efficiency over 2.7% [1, 2, 4, 5] and made into devices for light-emitting diode applications.

Description

Chemical Properties

solid

Uses

Pentacene can be used as OPV device (Organo Photovoltaic) and as semiconductors.

Uses

Pentacene is a polycyclic aromatic compound found in wastewater treatment facility units.

Definition

ChEBI: An acene that consists of five ortho-fused benzene rings in a rectilinear arrangement.

General Description

TGA/DSC Lot specific traces available upon request

Purification Methods

It forms blue crystals from *benzene or nitrobenzene and sublimes in a vacuum. [Clar & John Ber 62 940 1929, 64 981 1931, Beilstein 5 IV 2721.]
