[0029] Example 1
[0030] When X is Y is A is When the acceptor material BT-IC is prepared, the steps are as follows:
[0031] (1) Synthesis of compound 1: In a 150mL round bottom flask, add 2mol p-hexylbromobenzene and 100mL tetrahydrofuran under the protection of argon, cool the mixed solution to -78℃, and then add 2mol n-butyllithium dropwise to it After the addition is complete, stir at -78°C for 60 minutes, then add 0.3mol 2,2'-(4,8-bis(alkoxy)benzo[1,2-b:4,5-b'] Dithiophene-2,6-)bis(thiophene-3-carboxylic acid ethyl ester) was dissolved in 100 mL of tetrahydrofuran and then added dropwise to the above round bottom flask. After the addition, the temperature was raised to room temperature and stirring continued for 4 hours. After the reaction was completed, use Extract with dichloromethane, wash with water, dry with anhydrous sodium sulfate, spin-dry the solvent, and dissolve in 200mL of acetic acid solution, reflux for 30min, then add 1mL of concentrated sulfuric acid drop...
