Pentacene

??? C??? ??, ??, ??

??

Pentacene, an acene with flat-like molecules made of five linearly-fused benzene rings, has been extensivelystudied as a p-type semiconductor in organic field-effecttransistors. It is known to exhibit large carrier mobilitiesof about 1 cm2 /V s within the plane parallel to thesubstrate.

??? ??

solid

??

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

??

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

?? ??

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.]
