the invention relates to novel polymers of benzodithiophene, methods and materials for their preparation, their use as semiconductors in organic electronic (OE) devices, and to OE devices comprising these polymers.
Methods of adding substituents to a benzodithiophene are disclosed. A benzodithiophene is reacted with a reagent to directly add the substituent to the benzene core of the benzodithiophene. This method eliminates steps from prior process and eliminates the need for hydrogenation, allowing for a safer and more scaleable process. The resulting benzodithiophenes are suitable for use in semiconductor polymers and have no loss of performance.
