Embodiment 1
[0028] Add 0.351g 1,3,5-tris(4-aminophenyl)benzene, 0.210g trialdehyde phloroglucinol to 7mL 1,3,5-trimethylbenzene and 7mL 1,4-dioxane 1 mL of 3 mol / L glacial acetic acid was added dropwise to the mixed solution, and it was sonicated for 30 min until it was completely dissolved. Under vacuum, react at 150 °C for 60 h, then add 6 mL of N,N-dimethylformamide to the reaction solution, and continue the reaction for 24 h. Washed with 1,4-dioxane for 3 times and dried at 80 °C for 7 h to obtain a three-dimensional COFs structure material with ketone groups.
[0029] 50mg of three-dimensional COFs structure material was added to 20mL of water, 0.5mL of 3mol / L acetic anhydride solution was added dropwise to the above reaction solution, stirred at 75°C for 26h for ketone group addition, the reaction was cooled to room temperature, washed 3 times, and dried. Then the double hydroxyl structure material is obtained.
