Embodiment 1
[0111] Example 1 :Synthesis of 2,6-dibromo-di(dodecyl)-4,8-benzodithiophene dicarboxylate
[0112] According to the following scheme, 2,6-dibromo-di(dodecyl)-4,8-benzodithiophene dicarboxylate was synthesized.
[0113]
[0114] In a single-neck flask, 3-thienylmalonic acid (10.0 g, 53.7 mmol) and 1-dodecanol (4 equivalents, 40.0 g, 215 mmol) were dissolved in THF (80 mL) at room temperature. To this solution was added methanesulfonic acid (1.99 g, 20.7 mmol). The reaction mixture was stirred at room temperature for 3 days. The solvent was then evaporated at 40°C. By column chromatography (eluent: CH 2 Cl 2 ) The residue was purified to obtain compound 1 (yield: 18.0 g, 69%). 1 HNMR(CDC1 3 ): 0.9(6H,t), 1.3(36H,m), 1.7(4H,m), 4.2(4H,t), 4.8(1H,s), 7.2(1H,d), 7.3(1H,d) , 7.4(1H,s).
[0115] Prepare Fe(ClO) in a two-neck flask under argon at 0℃ 4 ) 3 Solution in methanol (320 mL), and to the solution was added a dispersion of compound 1 in methanol (120 mL). After the resulting so...

[0118] Example 2 : Synthesis of polymer 1
[0119]
[0120] The 2,6-dibromo-di(dodecyl)-4,8-benzodithiophene dicarboxylate (1.6g, 2.07mmol) obtained in Example 1 was placed in a two-necked flask and used vacuum- The argon gas is cycled three times. 300 mL of freshly distilled THF was added to the above flask via cannula and cooled to -78°C. At -78°C, a solution of 2.85M n-butyllithium in hexane (2.18 mL, 3 equivalents; 6.22 mmol) was added dropwise to the above solution. After the solution was subsequently stirred at -78°C for 1 hour, 1.0 M trimethyltin chloride in hexane (7.25 mL, 7.25 mmol) was added all at once. The reaction mixture was warmed to room temperature and stirred at room temperature for two hours. The mixture was then quenched by adding water (200 mL). After extracting the mixture three times with diethyl ether, the organic layers were combined, washed with brine solution, dried over anhydrous magnesium sulfate, and concentrated at room temperature under high ...
Embodiment 3
[0122] Example 3 : 1,4-bis(2-bromo-4,4'-bis(2-ethylhexyl)dithieno[3,2-b:2',3'-d]silole)-2,3, Synthesis of 5,6-Tetrafluorobenzene
[0123]
[0124] 4,4'-bis(2-ethylhexyl)dithieno[3,2-b:2',3'-d]silole (1.68 g, 4.0 mmol) was dissolved in 50 mL of dry THF. After the solution was cooled to -78°C, BuLi (1.40 mL, 4.0 mmol) was added thereto. After stirring the reaction mixture at -78°C for 30 minutes, the SnMe 3 Cl (4.0 mL, 4.0 mmol) was added to the reaction flask. The reaction mixture was then warmed to room temperature. Dissolve 1,4-dibromo-2,3,5,6-tetrafluorobenzene (0.61g, 2.0mmol) and bis(triphenylphosphine) palladium(II) chloride (0.14g, 0.20mmol) in 5mL THF. The resulting solution is then added to the above solution via a syringe. The reaction mixture was then refluxed overnight. After the reaction was cooled, it was quenched with water and extracted by dichloromethane. The crude product was concentrated by rotary evaporation, and purified by column chromatography to obt...
