2-D zinc coordination polymer with dual penetration structure as well as synthesis method and application of 2-D zinc coordination polymer

[0021] Specific embodiment 1: The molecular formula of a 2-D zinc coordination polymer with a double penetrating structure in this embodiment is C 20 h 10 N 6 o 4 Zn contains a central metal zinc ion and two 4-(1-triazolylmethylene) benzoic acid ligands in its basic structural unit; wherein, the central metal zinc ion presents a four-coordinated tetrahedral configuration, It coordinates and bonds with the nitrogen atom N1 of a 4-(1-triazolylmethylene)benzoic acid ligand and the N1A at its symmetrical position, and forms a bond with another 4-(1-triazolylmethylene) ) The oxygen atom O2 of the benzoic acid ligand and the O2A at its stacked position are coordinated to form a bond.

[0022] Two adjacent zinc ions are connected through the coordination oxygen atom and nitrogen atom of the 4-(1-triazolylmethylene) benzoic acid ligand to form a one-dimensional chain structure, and the adjacent chains are connected by Coordinating atoms of 4-(1-triazolylmethylene)benzoic acid liga...

[0024] Specific embodiment two: a kind of synthesis method of the 2-D zinc coordination polymer with double through structure of this embodiment is carried out according to the following steps:

[0025] 1. Preparation of ligand 4-(1-triazolylmethylene)benzoic acid: after mixing 4-chloromethyl benzyl cyanide, triazole, sodium hydroxide and N,N-dimethylformamide , and reacted for 10-20 hours under the condition of temperature 140-180°C to obtain 4-(1-triazolylmethylene)benzoic acid; wherein, the 4-chloromethyl benzyl cyanide and triazole The mol ratio is 1: (0.5~3), the mol ratio of described 4-chloromethyl benzyl cyanide and sodium hydroxide is 1: (0.5~3), described 2,2 '-biimidazole and The ratio of mass to volume of N,N-dimethylformamide is 3.03g: (30~70)mL;

[0026] 2. Put the 4-(1-triazolylmethylene)benzoic acid and zinc acetate prepared in step 1 in distilled water, stir at room temperature until evenly mixed, adjust the pH value of the system to 3-6, and put it into the ...

[0032]Embodiment 3: This embodiment is different from Embodiment 2 in that: in step 1, the reaction is carried out at a temperature of 160° C. for 12 hours. Other steps and parameters are the same as in the second embodiment.
