[0025] The present invention also provides a method for preparing the above-mentioned novel copper-metal organic framework material, which is characterized by comprising: preparing a copper source, 2,2'-bis(4-carboxyphenyl)hexafluoropropane in a solvent Solvothermal reaction; wherein the solvent contains DMF.
[0026] In the above preparation method, the specific conditions of the solvothermal reaction can be selected in a wide range, but in order to further improve the reaction rate and the yield of the novel copper-metal organic framework material, preferably, the solvothermal reaction satisfies the following conditions: reaction temperature It is 60-80℃, and the reaction time is 48-72h.
[0027] In the above preparation method, the amount of each material can be selected in a wide range, but in order to further improve the reaction rate and the yield of the new copper-metal organic framework material, preferably, copper source, 2,2'-bis(4 -carboxyphenyl) hexafluoropropane ...
Embodiment 1
[0039] 7.5 mg, 0.019 mmol of 2,2'-bis(4-carboxyphenyl)hexafluoropropane (H 2 L) and 24.16 mg, 0.1 mmol Cu(NO 3 ) 2 ·3H 2 O into a 10mL reaction flask, followed by DMF / H 2 O mixed solvent (volume ratio of 3:1, a total of 6 mL) was ultrasonicated at 25°C for 3-5min; then the mixed solution in the reaction flask was loaded into a stainless steel reaction kettle lined with PTFE, and the solvent was heated at 70°C Thermal reaction for 60h; finally cool down slowly, cool to room temperature (25°C) for solid-liquid separation, use the reacted mixed solution to take the supernatant, wash the solid complex for many times, and then place the complex to dry naturally at room temperature to obtain Few blue bulk crystals, yield 66.83%.
Embodiment 2
[0041] It was carried out according to the method of Example 1, except that the solvothermal reaction was carried out at 60° C. for 72 h, and the yield was 68.26%.
