Embodiment 1

[0041] Choose the best ratio of raw materials:

[0042]

[0043]After X-ray single crystal diffraction test, when the molar ratio 1,3,5-tris(imidazolylmethyl)-2,4,6-trimethylbenzene:phthalic acid:zinc acetate dihydrate=2:3 : When 3, the obtained crystal is more complete, transparent and of higher quality.

Embodiment 2

[0045] The preparation of the complex constructed by the flexible trimidazole ligand specifically adopts the following steps:

[0046] Step 1: Put 1,3,5-tris(imidazolylmethyl)-2,4,6-trimethylbenzene, phthalic acid, and zinc acetate dihydrate at a molar ratio of 2:3:3 in water In the mixed solution of water and ethanol, wherein the volume ratio of water and ethanol is (3-4): 1, stir at room temperature to obtain a mixed suspension, and set aside;

[0047] Step 2: Transfer the mixed suspension obtained in step 1 to a reaction kettle, the volume of the mixed suspension accounts for 1 / 2 to 2 / 3 of the volume of the reaction kettle, and react at 150°C to 180°C After 2-4 days, cool down to room temperature at a cooling rate of (8-10)° C. / h to obtain colorless crystals, which are complex crystals constructed with flexible trimidazole ligands in the present invention.

Embodiment 3

[0049] Adopt the preparation method of embodiment 2, concrete reaction conditions and corresponding product label obtained are as follows:

Description

technical field [0001] The invention relates to a complex with a 2D layered structure, in particular to a complex composed of 1,3,5-tris(imidazolylmethyl)-2,4,6-trimethylbenzene, phthalic acid, and zinc acetate The preparation method of the complex. Background technique [0002] In recent years, coordination polymers have attracted the attention of chemists due to their novelty, captivating topological structure and wide application of physical and chemical properties, such as gas storage and separation, selective catalysis, and luminescent properties. The flexible N-containing ligands have the following characteristics: 1) The N atom has strong coordination ability and is easy to protonate; 2) Due to the flexibility of its skeleton structure, it is easy to bend during the self-assembly process and can be formed according to the central atom. Therefore, the imidazole derivatives in flexible ligands have been widely concerned and applied. [0003] Due to the existence of ar...
