Abstract
The invention relates to new thienothiophene derivatives, their use as semiconductors or charge transport materials, in optical, electrooptical or electronic devices like for example organic field effect transistors (FET or OFET) for thin film transistor liquid crystal displays and integrated circuit devices such as RFID tags, electroluminescent devices in flat panel displays, and in photovoltaic and sensor devices, and to a field effect transistor, light emitting device or ID tag comprising the thienothiophene derivatives.
