Embodiment 1
[0039] The synthesis of the covalent organic framework material NKCOF-108 with a biomimetic structure, the specific implementation steps are as follows:
[0040] Weigh the monomer 4,4'-((5-fluorobenzo[c][1,2,5]thiadiazole-4,7-diyl)bis(acetylene-2,1-diyl)) Dibenzaldehyde (0.04mmol) and 1,3,6,8-tetrakis-(p-aminophenyl)-pyrene (0.02mmol) were added into a thick-walled heat-resistant glass tube (o.d.×i.d=10×8mm 2 ), then add 0.95mL of mesitylene, 0.05mL of n-butanol and 0.1mL of 6M acetic acid aqueous solution, then quickly freeze in liquid nitrogen, then vacuumize, and then seal the tube with a flame of an oxygen hydrogen machine. Put the sealed glass tube into an oven at 120°C for 5 days to react to obtain dark red solid product NKCOF-108. Its PXRD as Figure 4 shown.
Embodiment 2
[0042] The synthesis of the covalent organic framework material NKCOF-109 with a biomimetic structure, the specific implementation steps are as follows:
[0043]Weigh the monomer 4,4'-((5,6-difluorobenzo[c][1,2,5]thiadiazole-4,7-diyl)bis(acetylene-2,1-diyl) Base)) benzaldehyde (0.04mmol) and 1,3,6,8-tetra-(p-aminophenyl)-pyrene (0.02mmol) were added into a thick-walled heat-resistant glass tube (o.d.×i.d=10×8mm 2 ), then add 0.1mL mesitylene, 0.9mL n-butanol and 0.1mL 6M acetic acid aqueous solution, then quickly freeze in liquid nitrogen, then vacuumize, and then seal the tube with a flame of an oxygen hydrogen machine. Put the sealed glass tube into an oven at 120°C for 5 days to react to obtain dark red solid product NKCOF-109. Its PXRD as Figure 4 shown.
Embodiment 3
[0045] The synthesis of the covalent organic framework material NKCOF-110 with a biomimetic structure, the specific implementation steps are as follows:
[0046] Weigh the monomer 4,4'-(benzo[c][1,2,5]thiadiazole-4,7-diylbis(ethyn-2,1-diyl))benzaldehyde (0.04 mmol) and 1,3,6,8-tetra-(p-aminophenyl)-pyrene (0.02mmol) into thick-walled heat-resistant glass tube (o.d.×i.d=10×8mm 2 ), then add 0.75mL of mesitylene, 0.25mL of n-butanol and 0.1mL of 6M acetic acid aqueous solution, then quickly freeze in liquid nitrogen, then vacuumize, and then seal the tube with a flame of an oxygen hydrogen machine. Put the sealed glass tube into an oven at 120°C for 5 days to react to obtain dark red solid product NKCOF-110. Its PXRD as Figure 4 shown.
