Embodiment 1
[0035] In a 50mL round bottom flask, will contain 242mg (1mmol) of Cu(NO 3 ) 2 ·3H 2 O and 314 mg (1 mmol) of Na 2 B 12 h 11 I was dissolved in 10 ml of water. In another 25 mL round bottom flask, 360 mg (2 mmol) of 4,4'-bipyridylacetylene was dissolved in 15 mL of methanol. The methanol solution was slowly added to the aqueous solution, and stirred at 25°C for 24 hours to obtain a gray-purple solid precipitate, which was filtered and washed with methanol. Replace the above solid in anhydrous methanol 3 times with an interval of 12 hours each time to remove the water molecules in the pores of the material, and then degas and activate it at 70°C for 10 hours to obtain the activated functionalized caged dodecaborane anion supramolecule The microporous frame material is named BSF-20.
[0036] The self-assembly behavior of BSF-20 is as figure 1 shown. First, metallic copper ions are coordinated to four different pyridine rings in the horizontal direction and to B–H of two...
Embodiment 2
[0054] In a 50mL round bottom flask, will contain 242mg (1mmol) of Cu(NO 3 ) 2 ·3H 2 O and 314 mg (1 mmol) of Na 2 B 12 h 11 I was dissolved in 10 ml of water. In another 25 mL round bottom flask, 312 mg (2 mmol) of bipyridyl was dissolved in 15 mL of methanol. The methanol solution was slowly added to the aqueous solution, and stirred at 25° C. for 2 h to obtain a gray-purple solid precipitate, which was filtered and washed with methanol. Replace the above solid in anhydrous methanol 3 times with an interval of 12 hours each time to remove the water molecules in the pores of the material, and then degas and activate it at 80°C for 5 hours to obtain the activated functionalized caged dodecaborane anion supramolecule Microporous frame material, named BSF-21.
Embodiment 3
[0056] In a 50mL round bottom flask, will contain 242mg (1mmol) of Cu(NO 3 ) 2 ·3H 2 O and 314 mg (1 mmol) of Na 2 B 12 h 11 I was dissolved in 10 ml of water. In another 25 mL round bottom flask, 464 mg (2 mmol) of bipyridylbenzene was dissolved in 15 mL of methanol. The methanol solution was slowly added to the aqueous solution, and stirred at 25°C for 48 hours to obtain a gray-purple solid precipitate, which was filtered and washed with methanol. Replace the above solid in anhydrous methanol 3 times with an interval of 8 hours each time to remove the water molecules in the pores of the material, and then degas and activate it at 100°C for 10 hours to obtain the activated functionalized caged dodecaborane anion supramolecule Microporous frame material, named BSF-22.
