    摘要: A process of dissolving 3-fluoro-4,6-dihydrothieno[3,4-b]thiophene in a solvent to create a solution. An initiator is then added to the solution to produce an initiated solution followed by adding a fluorinated chemical to the initiated solution to produce 2,3-difluoro-4,6-dihydrothieno[3,4-b]thiophene. 2,3-difluoro-4,6-dihydrothieno[3,4-b]thiophene is then oxidized with an oxidant to produce 2,3-difluorothieno[3,4-b]thiophene. A brominating step then occurs to the 2,3-difluorothieno[3,4-b]thiophene to produce 4,6-dibromo-2,3-difluorothieno[2,3-c]thiophene 4,6-dibromo-2,3-difluorothieno[2,3-c]thiophene is then debrominated and polymerized to The stoichiometric ratio of (f+g)≈h and f, g and h are not equal to 0. Additionally, in this embodiment R1, R2, R3 and R4 are independently selected from the group consisting of alkyl group, alkoxy group, aryl groups and combinations thereof and where the combination of R1, R2, R3 and R4 are not all identical.
