Embodiment 1

[0119] Preparation of an organic monomer and four conjugated polymers

[0120] ①Synthesis of compound 1

[0121] Under an argon protective atmosphere, 7 mL of diisopropylamine was added to 18 mL of anhydrous tetrahydrofuran solution and fully stirred, and under ice bath conditions, 5 mL of borane dimethyl sulfide in tetrahydrofuran (10 mol / L) was added dropwise In the above reaction solution, after the dropwise addition, the reaction was continued for 1.5 hours under ice-bath conditions; Stir for 2 hours; finally, add 6.4 mL of trimethylchlorosilane dropwise to the reaction system, and immediately produce a large amount of white precipitates, and stir at room temperature for 2 hours after all the addition. After the reaction, the reaction solution was left to stand for 1 hour and filtered under the protection of argon to obtain a colorless and transparent filtrate which was compound 1, which was stored under the protection of argon for future use, with a yield of about 99%. ...

Embodiment 2

[0143] In this example, in step ① of the synthesis of compound 1, 7 mL of diisopropylamine was added to 32.5 mL of anhydrous tetrahydrofuran solution under an argon protective atmosphere and fully stirred, and 5 mL of diisopropylamine was added dropwise under ice bath conditions The tetrahydrofuran solution (10mol / L) of borane dimethyl sulfide was added to the above reaction solution. After the dropwise addition, the reaction was continued for 1.5 hours under ice bath conditions; then 20 mL of n-butyl lithium was added dropwise to the reaction system n-Hexane solution (2.5mol / L), continue to stir for 2 hours under ice-bath conditions; finally, add 6.4mL trimethylchlorosilane dropwise to the reaction system, a large amount of white precipitate will be produced immediately, after all the addition, stir at room temperature 2 hours. The molar ratio of diisopropylamine, borane dimethyl sulfide, n-butyllithium, trimethylchlorosilane and tetrahydrofuran is 1:1:1:1:5.5. After the rea...
