Hexacene is one of a series of linear acenes, the previous one being pentacene ( five fused benzene rings ) and the next one being heptacene ( seven fused benzene rings ).

A few other conjugated pentacene polymers ( "'2a b "'and "'3 "') have been realized based on Sonogashira and Suzuki coupling reactions of a dibromopentacene monomer.

If the pentacene is preoxidized, the pentacene-quinone is a potential gate insulator, then the mobility can approach that of rubrene the highest-mobility organic semiconductor namely, 40 cm 2 / ( V�s ).

Pentacene is a popular choice for research on organic thin-film transistors and OFETs, being one of the most thoroughly investigated conjugated organic molecules with a high application potential due to a hole mobility in OFETs of up to 5.5 cm 2 / ( V�s ), which exceeds that of amorphous silicon.
36.
The choice of the substituents ( both size and location of substitution on the pentacene ) influences the solid-state packing and can be used to control whether the compound adopts 1-dimensional or 2-dimensional cofacial pi-stacking in the solid-state, as opposed to the herringbone packing observed for pentacene.

OFETs employing many aromatic and conjugated materials as the active semiconducting layer have been reported, including small molecules such as rubrene, tetracene, pentacene, diindenoperylene, perylenediimides, tetracyanoquinodimethane ( TCNQ ), and polymers such as polythiophenes ( especially poly ( 3-hexylthiophene ) ( P3HT ) ), polyfluorene, polydiacetylene, poly ( 2, 5-thienylene vinylene ), poly ( p-phenylene vinylene ) ( PPV ).
