Embodiment 1
[0028] Add 0.351 g of 1,3,5-tris(4-aminophenyl)benzene, 0.210 g of trialdehyde phloroglucinol to 7 mL of 1,3,5-trimethylbenzene and 7 mL of 1,4-dioxane Add 1mL of 3mol / L glacial acetic acid dropwise to the mixed solution, and sonicate for 30min until 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. After washing with 1,4-dioxane three times and drying at 80°C for 7 hours, a three-dimensional COFs structure material with ketone groups was obtained.
[0029] Add 50mg of three-dimensional COFs structure material to 20mL of water, drop 0.5mL of 3mol / L acetic anhydride solution into the above reaction solution, stir at 75°C for 26h for ketone addition, cool the reaction to room temperature, wash 3 times, and dry After that, the double hydroxyl structure material is obtained.
