Embodiment 1

[0040] When X is an S atom, A is R is The prepared chemical structure is The preparation steps of the transistor material PIM-DTF with an n value of 1-100 are as follows:

[0041] (1) Synthesis of Compound 1: In a 250mL round-bottomed flask, 4.76g of diisopropylamine and 100mL of tetrahydrofuran were added under the protection of argon, the mixed solution was cooled to -78°C, and 19.2mL of n-butyllithium was added dropwise thereto Solution, after the dropwise addition, stirred at -78°C for 40min, then dissolved 6.01g of ethyl thiophene-3-carboxylate in 500mL of tetrahydrofuran and added dropwise to the mixed solution in the round bottom flask, after the dropwise addition, continued to stir After 1 hour, 46.1 mL of trimethyltin chloride was added dropwise. After 1 hour of reaction, the reaction liquid was heated to room temperature and stirred for 5 hours. After the reaction was completed, it was extracted with ethyl acetate, washed with water, dried with anhydrous sodium ...
