NOVELTY - A process involving: dissolving 3-fluoro-4,6-dihydrothieno(3,4-b)thiophene in a solvent to create a solution; adding an initiator to the solution to produce an initiated solution; adding a fluorinated chemical to the initiated solution to produce 2,3-difluoro-4,6-dihydrothieno(3,4-b)thiophene; oxidizing 2,3-difluoro-4,6-dihydrothieno(3,4-b)thiophene with an oxidant to produce 2,3-difluorothieno(3,4-b)thiophene; brominating 2,3-difluorothieno(3,4-b)thiophene to produce 4,6-dibromo-2,3-difluorothieno(2,3-c)thiophene.    USE - The process is useful for producing multi-component benzo(1,2-B:4,5-B)dithiophene-difluorothienothiophene polymer, for producing a photovoltaic material for use in photovoltaic devices used as a polymer solar cell device or photodetector device, and for producing an active layer material for one or more electronic devices, where the electronic devices are field effect transistors, light emitting devices, and sensors, electrochromic devices and capacitors (all claimed).    ADVANTAGE - The process produces multi-component benzo(1,2-B:4,5-B)dithiophene-difluorothienothiophene polymer used as a photovoltaic material for use in manufacturing polymer solar cells that exhibit increased solar conversion efficiency.
