Embodiment 1
[0042] This embodiment is the preparation of metal coordination polymers, and the specific preparation steps are as follows:
[0043] 1) Weigh bipyrazole (5.0mg, 0.026mmol) and CuSCN (5.0mg, 0.041mm) respectively into glass tubes with an outer diameter of 8mm;
[0044] 2) Then add acetonitrile (1mL) and deionized water (0.1mL) respectively, and sonicate for 2min;
[0045] 3) Seal the glass nozzle with a hydrogen-oxygen machine, put it into an electric blast drying oven after ultrasonication for 30 minutes, heat up to 140°C within 10 minutes, then heat at 140°C for 48 hours, and finally cool down to room temperature within 2 hours. Obtained light yellow transparent flaky crystals. After washing with acetonitrile and acetone, the product was obtained after natural drying, and the yield was about 50.0%.
[0046] The structure of the coordination polymer based on pyrazole ring prepared in this example was characterized.
[0047] Crystalline X-ray diffraction data were collected...
Embodiment 2
[0057] This embodiment is to prepare metal coordination polymer by reflux method
[0058] 1) TCuSCN reflux synthesis steps: bipyrazole (70mg, 0.368mmol) and CuSCN (49mg, 0.403mmol) were added to a round bottom flask respectively;
[0059] 2) Add 7ml of acetonitrile and 0.7mL of deionized water (acetonitrile: water = 10:1), and reflux the mixture in an oil bath at 100°C for 4 hours;
[0060] 3) Suction filtration after cooling to room temperature, washing filter residue with acetonitrile, to remove excess bipyrazole;
[0061] 4) Dry naturally to obtain light yellow powder with a yield of 67.2%.
Embodiment 3
[0063] This example is the preparation of metal coordination polymers by reflux in acetonitrile
[0064] 1) Weigh bipyrazole ligand (100.0mg, 0.526mmol) and CuSCN (56mg, 0.460mmol) into a 50mL round bottom flask;
[0065] 2) Add acetonitrile (25mL) in the round bottom flask;
[0066] 3) Reflux in an oil bath at 90°C for 2 hours, cool to room temperature after the reaction is complete, filter with suction, and wash the filter residue with acetonitrile;
[0067] 4) Dry naturally to obtain light yellow microcrystalline powder with a yield of 79.9%.
[0068] The metal coordination polymers prepared in Example 2 and Example 3 were characterized by infrared and X-ray powder diffraction structures.
[0069] Figure 7 It is a comparison chart of the infrared absorption spectra of the metal coordination polymers prepared in Examples 2 and 3 and Example 1. It can be seen from the figure that the infrared spectra of the metal coordination polymers prepared in Examples 2 and 3 are the...
