Embodiment 1
[0036] Synthesis of polymer P1
[0037] The representative synthetic route is as follows:
[0038]
[0039] Synthesis of polymer P1:
[0040] Accurately weigh the monomer M1 (0.275 mmol, 0.1419 g) and monomer M2 (0.275 mmol, 0.2027 g), and a 48 ml thick wall withstand bottle was added to add 10 ml of toluene, 5 wt% palladium catalyst, sealed in an inert gas environment. A protected reaction was protected from light at 120 ° C for 48 h. After cooling to room temperature, the reaction solution was dripped into a solution of methanol, and the crude product was filtered. The crude product was subjected to Supreme Extraction of the Soda with 100 mL of methanol, petroleum ether, dichloromethane, and chlorobenzene solvent, and the remaining solid was rinsed with methanol, and the solid product P1 was obtained. The P1 m was 4, N 500.
[0041] The photocatalyst of the present embodiment consists of conjugated polymer P1.
Embodiment 2
[0043] Synthesis of polymer P2
[0044] The representative synthetic route is as follows:
[0045]
[0046] Synthesis of polymer P2:
[0047] Accurately weigh the monomer M3 (0.306 mmol 0.1425 g) and monomer M2 (0.306 mmol 0.2254 g), adding 48 ml thick wall withstand bottles, 10 ml of toluene, 5 wt% palladium catalyst, sealed under an inert gas environment. A protected reaction was protected from light at 120 ° C for 48 h. After cooling to room temperature, the reaction solution was dripped into a solution of methanol, and the crude product was filtered. The crude product was subjected to each 24 h, and the residue solid was rinsed with methanol, and the solid product P2 was rinsed with methanol, and the solid product P2 was obtained. Take 500.
[0048] The photocatalyst of the present embodiment consists of conjugated polymer P2.
Embodiment 3
[0050] The preparation method of the present embodiment is in Example 1, and the main difference is that the M1 monomer is replaced into a D3 monomer. The P3 conjugated polymer was obtained, and the P3 of M is 4, N is 500.
[0051] The photocatalyst of the present embodiment consists of conjugated polymer P3.
