The archetypal organic oligomer used as the semiconductor in thin film field effect transistors. Can be vapour deposited or in potentially an ink viaprecursor. Needs vacuum processes because it is insoluble but gives higher charge carrier mobility than the soluble organic semiconductors that can be printed. This means that the transistors can work at higherfrequencyand be used in more applications technically, though cost is a challenge. Recently, there has been progress towards makingpentacenedirectly printable.
