Embodiment 1
[0036] Example 1 Synthesis of 2,5-bis(bismethoxyoctylsilyl)-PPV: the structural formula is as follows:
[0037]
[0038] (1) Synthesis of 1,4-bis(bismethoxyoctylsilyl)benzene: 10.0 grams (42mmol) of p-dibromobenzene was dissolved in 100ml of anhydrous tetrahydrofuran, and N 2 For protection, 50ml (100mmol) of 2M freshly prepared n-butyllithium tetrahydrofuran solution was slowly added dropwise at -78°C, and after maintaining the temperature for 3 hours, 20g (84mmol) dimethoxyoctane was slowly added dropwise at -78°C Chlorosilane, after 2 hours of reaction, the temperature was slowly raised to room temperature within 3 hours, and the reaction was completed at room temperature for 6 hours. The reactant was washed with water, dried and distilled under reduced pressure to obtain the product. Boiling point: 173°C / 0.2mmHg.
[0039] The analytical results of the product are as follows:
[0040] 1 H NMR (R3DR3l3 ): δ (ppm) 7.08 (4H, singlet, R1r-H), 1.45-1.15 (24H, multiplet), ...
Embodiment 2
[0049] Example 2 Synthesis of 2,5-bis(methoxybutoxyoctylsilyl)-PPV: the structural formula is as follows:
[0050]
[0051] (1) Synthesis of 1,4-bis(methoxybutoxyoctylsilyl)benzene: 10.0 grams of p-dibromobenzene (42mmol) were dissolved in 500ml of anhydrous tetrahydrofuran, passed into N 2 For protection, 100ml (200mmol) of 2M freshly prepared n-propyllithium tetrahydrofuran solution was slowly added dropwise at -70°C, and the reaction was maintained at this temperature for 3 hours. 40 g (142 mmol) of methoxybutoxyoctylchlorosilane was slowly added dropwise at -70°C, and after 2 hours of reaction, the temperature was slowly raised to room temperature within 3 hours, and the reaction was completed at room temperature for 12 hours. The reactant was washed with water, dried and distilled under reduced pressure to obtain the product. Boiling point: 181°C / 0.2mmHg.
[0052] The analytical results of the product are as follows:
[0053] 1 H NMR (R3DR3l 3 ): δ (ppm) 7.06 (4H,...
Embodiment 3
[0062] Example 3 Synthesis of 2,5-bis(methyloctyloctadecylsilyl)-PPV: the structural formula is as follows:
[0063]
[0064] (1) Synthesis of 1,4-bis(methyloctyloctadecylsilyl)benzene: 10.0 grams (42mmol) of p-dibromobenzene are dissolved in 200ml of anhydrous tetrahydrofuran, and N 2 For protection, 120ml (240mmol) of fresh 2M isooctyllithium tetrahydrofuran solution was slowly added dropwise at -80°C, and the reaction was maintained at this temperature for 8 hours. Slowly add 130 g (292 mmol) of methyloctyloctadecylchlorosilane dropwise at -80°C. After 5 hours of reaction, the temperature is slowly raised to room temperature within 3 hours, and the reaction is completed at room temperature for 12 hours. The reactant was washed with water, dried and distilled under reduced pressure to obtain the product. Boiling point: 168°C / 0.1mmHg.
[0065] The analytical results of the product are as follows:
[0066] 1 H NMR (R3DR3l 3 ): δ (ppm) 7.23 (4H, singlet, R1r-H), 1.50-1....
