preparation example Construction

[0053] The preparation method of the present invention has the porous polymer material of ultra-high specific surface area, comprises the following steps:

[0054] Step 1, adding bis-1,5-cyclooctadiene nickel, 2,2-bipyridine and 1,5-cyclooctadiene into N,N-dimethylformamide or toluene solution, Put it into an oil bath preheated to 20°C-140°C to age the catalyst for 0.5-3 hours;

[0055] Step 2, add the N,N-dimethylformamide or toluene solution of p-bromotetraphenylmethane or p-iodotetraphenylmethane corresponding to the number of moles, so that the concentration of the reactant remains between 0.001M-5M, while ensuring that the double The ratio of 1,5-cyclooctadiene nickel to halogen atoms is between 0.6-1.5;

[0056] Step 3, keeping the above solution at temperature, reacting for 10 minutes to 5 days, and stopping the reaction;

[0057] Step 4, adding concentrated hydrochloric acid to the reaction system to destroy the remaining double 1,5-cyclooctadiene nickel;

[0058] S...

Embodiment 1

[0078] (1) 1g of double 1,5-cyclooctadiene nickel, 0.568g 2,2-bipyridine and 0.4mL of 1,5-cyclooctadiene were added to 1mL of N,N-dimethylformamide solution, Put it into an oil bath preheated to 60°C to age the catalyst for 0.5-3 hours;

[0079] (2) Then 3 mL of 0.2 M p-bromotetraphenylmethane N, N-dimethylformamide, react at this temperature for 60 hours, and stop the reaction;

[0080] (3) Add concentrated hydrochloric acid in reaction system, destroy excessive 1,5-cyclooctadiene nickel, filter to obtain pale yellow precipitate;

[0081] (4) Wash with hot solutions of 100mL water, 100mL tetrahydrofuran and 100mL chloroform to remove inorganic salts and soluble organic matter;

[0082] (5) The final product was vacuum-dried at 80-200°C for 10-40 hours (vacuum degree less than 10-3 mmHg) to obtain a polymer with a yield of 76%.

[0083] As shown in Figure 2, it is the infrared contrast spectrogram of the porous polymer material and the reaction monomer prepared by p-bromotet...

Embodiment 2

[0096] The mixed solution in step (1) of Example 1 was moved to a stainless steel vacuum reactor, the reaction temperature was changed to 80° C., and the other conditions were unchanged, and the same material as described in Example 1 was obtained.

Description

technical field [0001] The invention relates to the field of functional materials, in particular to a porous polymer material with an ultra-high specific surface area, its preparation method and its application in gas storage or liquid adsorption. Background technique [0002] Today, materials, energy, and information are listed as the three pillars of modern science and technology, and their role and significance are self-evident. Among a variety of materials that are constantly being developed and applied, porous materials have always attracted the attention of researchers all over the world. Due to the open structure of porous materials, they are widely used in many fields, such as ion exchange, adsorption and separation, and host-guest chemistry. Initially, porous materials were studied as materials with specific pore structure constructed by inorganic species. This includes microporous materials with a pore size of less than 2 nm, mesoporous materials with a pore size...
