An organic field-effect transistor (OFET) is a field-effect transistor utilizing organic molecules or polymers as the active semiconducting layer. A field-effect transistor ([[FET]]) is any semiconductor material that utilizes [[electric field]] to control the shape of a channel of one type of [[charge (physics)|charge]] carrier, thereby changing its conductivity. Two major classes of [[FET]] are n-type and p-type semiconductor, classified according to the charge type carried. In the case of organic FETs (OFETs), p-type OFET compounds are generally more stable than n-type due to the susceptibility of the latter to oxidative damage.

As for OLEDs, some OFETs are molecular and some are polymer-based system. [[Rubrene]]-based OFETs show high carrier mobility of 20–40&nbsp;cm<sup>2</sup>/(V·s). Another popular OFET material is [[Pentacene]]. Due to its low [[solubility]] in most organic [[solvent]]s, it's difficult to fabricate thin film transistors ([[Thin-film transistor|TFTs]]) from pentacene itself using conventional spin-cast or, [[dip coating]] methods, but this obstacle can be overcome by using the derivative TIPS-pentacene.
