A method of producing a monomer wherein the method begins by 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. This is 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. 2,3-difluorothieno[3,4-b]thiophene is then bromoated to produce 4,6-dibromo-2,3-difluorothieno[2,3-c]thiophene. The final step involves debrominating 4,6-dibromo-2,3-difluorothieno[2,3-c]thiophene and adding an aryl group to produce the monomer
一种生产单体的方法,该方法从将3-氟-4,6-二氢噻吩[3,4-b]噻吩溶解于溶剂中开始,形成溶液。然后向该溶液中加入引发剂,以产生引发的溶液。接着向引发的溶液中加入氟化化学物质,以产生2,3-二氟-4,6-二氢噻吩[3,4-b]噻吩。然后使用氧化剂将2,3-二氟-4,6-二氢噻吩[3,4-b]噻吩氧化,以产生2,3-二氟噻吩[3,4-b]噻吩。接着将2,3-二氟噻吩[3,4-b]噻吩溴化,以产生4,6-二溴-2,3-二氟噻吩[2,3-c]噻吩。最后一步涉及脱溴4,6-二溴-2,3-二氟噻吩[2,3-c]噻吩,并添加芳基基团以产生单体。
