Embodiment Construction

[0018] An antibacterial copper metal coordination polymer is characterized in that: it has the following molecular formula:

[0019] [Cu(SO 4 2- )(en) 2 ] n , and its crystal structure data are as follows: orthorhombic system; Cmca space group; unit cell parameters a =1.4600(3)nm; b = 0.9691(2)nm; c = 1.4026(4)nm; α = 90.00º; β = 90.00°; gamma =90.00º; V = 1.9845(8) nm 3 ; Z = 8; D = 1.860 Mg∙m -3 .

[0020] n is an integer greater than 1, and the polymer is an infinite number of unit cell repeats.

[0021] Its crystal structure is as figure 1 shown.

[0022] Its preparation method is as follows:

[0023] Add 0.223mmol (30mg) CuCl to a 25mL polytetrafluoroethylene reactor lining 2 , 0.111mmol (20mg) of 1,10-phenanthroline, 8mL of DMF, 2mL of water, 0.07mL of ethylenediamine and an appropriate amount of sulfuric acid to adjust the pH, and fully stirred at room temperature for 1h. After stirring, the lining of the kettle was put into the kettle, seal...

Abstract

The invention discloses an antibacterial copper metal coordination polymer. The molecular formula of the antibacterial copper metal coordination polymer is [Cu(SO4<2->) (en)2] n. The antibacterial copper metal coordination polymer disclosed by the invention has a certain antibacterial property on Gram-negative bacteria escherichia coli and Gram-positive bacteria staphylococcus aureus, and it is found that the inhibition effect of the antibacterial copper metal coordination polymer on escherichia coli is superior to that on staphylococcus aureus.

Description

technical field [0001] The present invention relates to the performance research field of copper metal coordination polymer, especially a kind of coordination polymer [Cu(SO 4 2- )(en) 2 ] n , synthesis method and its inhibitory effect on Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus. Background technique [0002] Multifunctional materials represented by copper(II) coordination polymers have attracted more and more attention because of their novel structures and broad application prospects in catalysis, optics, separation, and antibacterial. At present, ethylenediamine compounds are widely used in the synthesis of organic and inorganic multifunctional materials due to their strong coordination ability, high reactivity and rich functions. Under solvothermal conditions, many multifunctional coordination polymers based on ethylenediamine compounds have been successfully synthesized by utilizing the synergistic effect of inorganic c...
