Embodiment 1
[0041] (1) Synthesis of the first monomer
[0042] Under the condition of 200°C, triethylamine was dehydrated with sodium hydroxide for later use, and toluene was dehydrated with metal sodium wire for later use. Take a round bottom flask for anhydrous and anaerobic treatment, then take 18ml of anhydrous triethylamine, 100ml of anhydrous toluene, and 3.9ml of glycidol in the flask and mix them in an ice ethanol bath until the temperature drops below -5°C , 5ml of sebacoyl chloride was added dropwise to the mixed solution at a rate of 10ml / h, and the reaction was carried out for 10h, accompanied by magnetic stirring during the reaction. After the reaction is terminated, the reaction product is filtered and purified by a chromatographic column to obtain a pure first monomer.
[0043] (2) Synthesis of PSeD-Azo
[0044] Get the first monomer (1mmol), the second monomer sebacic acid (0.5mmol), the third monomer azobenzene-4,4-dicarboxylic acid (0.5mmol), catalyst tetrabutylammoniu...
Embodiment 2
[0046] In Example 1, the first monomer (0.5mmol), the second monomer bisphenol F diglycidyl ester (0.5mmol), the third monomer azobenzene-4,4-dicarboxylic acid (1mmol), catalyst Tetrabutylammonium bromide (0.5mmol% of the carboxyl functional group) is placed in the reaction flask, and the solvent N, N'-dimethylformamide 9ml is added to the reaction flask at the same time, after anhydrous and anaerobic treatment, at 100 ° C Under nitrogen atmosphere, magnetic stirring was carried out for 18 h. After the reaction, the obtained product was washed three times with anhydrous ether, and vacuumized to obtain a light yellow solid organic photothermal polymer.
Embodiment 3
[0048] In Example 1, the first monomer (1mmol), the second monomer adipic acid (0.5mmol), the third monomer azobenzene-3,3-dicarboxylic acid (0.5mmol), the catalyst cetyl bromide Alkyltrimethylammonium (0.5mmol% of the carboxyl functional group) was placed in the reaction flask, and at the same time, 6ml of solvent dichloroethane was added to the reaction flask, and after anhydrous and oxygen-free treatment, it was magnetically stirred at 100°C for 24h under a nitrogen atmosphere. After the reaction, the obtained product was washed three times with absolute ethanol, and vacuumized to obtain a light yellow solid organic photothermal polymer.
