Embodiment 1
[0058] Example 1 Synthesis of [Co(L 1 ) 0.5 (5-AIP)], where L 1 It is N,N'-bis(3-pyridine)-succinamide, the structural formula is: , 5-AIP is 5-aminoisophthalate
[0059] 0.1mmol CoCl 2 ·6H 2 O, 0.10 mmol N,N'-bis(3-pyridine)-succinamide, 0.10 mmol 5-aminoisophthalic acid, and 7.5 mL H 2 O was sequentially added to a 25mL beaker, and stirred at room temperature for 20min to obtain a suspension mixture. After the pH of the suspension mixture was adjusted to 6.8 with 0.1mol / L NaOH solution, it was transferred to a 25mL autoclave. The heating rate was increased to 110°C, and the temperature was kept for 48 hours under hydrothermal conditions, and the temperature was lowered to room temperature at a cooling rate of 5°C / h to obtain pink blocky crystals, which were washed alternately with deionized water and ethanol for 4 times, and dried naturally at room temperature , get [Co(L 1 ) 0.5 (5-AIP)], productive rate is 45%, and its XRD diffraction pattern is as figure 1 As sh...
Embodiment 2
[0060] Example 2 Synthesis of [Co(L 1 ) 0.5 (5-AIP)], where L 1 N,N'-bis(3-pyridine)-succinamide, 5-AIP is 5-aminoisophthalate
[0061] 0.2mmol CoCl 2 ·6H 2 O, 0.10 mmol N,N'-bis(3-pyridine)-succinamide, 0.15 mmol 5-aminoisophthalic acid, and 9.0 mL H 2 O was sequentially added to a 25mL beaker, and stirred at room temperature for 30min to obtain a suspension mixture. After adjusting the pH of the suspension mixture to 7.2 with 0.1mol / L NaOH solution, it was transferred to a 25mL autoclave and heated at 5°C / h The temperature was raised to 120°C, kept under hydrothermal conditions for 96 hours, and the temperature was lowered to room temperature at a cooling rate of 15°C / h to obtain pink blocky crystals, which were washed alternately with deionized water and ethanol for 3 times, and dried naturally at room temperature. get [Co(L 1 ) 0.5 (5-AIP)], productive rate is 69%, and its XRD diffraction pattern is as figure 1 As shown, the coordination environment diagram is show...
