Methods for preparing benzodithiophenes |
| abstract |
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. |
