Acenes (sometimes referred to as polyacenes) form a functional class of organic compounds: they are polycyclic aromatic hydrocarbons made up of linearly fused benzene rings.[1] The larger acenes have potential interest in optoelectronic applications and as organic semiconductors.[2][3] Pentacene has been incorporated into organic field-effect transistors, reaching charge carrier mobilities as high as 5 cm2 V−1 s−1.[2] Unsubstituted acenes larger than pentacene have only been studied by matrix isolation techniques,[2][3][4] although substituted acenes up to nonacene have been isolated.[2][5]
