preparation example Construction
[0033] The present invention also provides a preparation method of the conjugated microporous polymer, comprising the following steps:
[0034] After mixing 2,4,6-trimethyl-1,3,5-triazine, trialdehyde phloroglucinol, inorganic base and anhydrous methanol, condensation reaction is carried out to obtain conjugated microporous polymer.
[0035] In the present invention, the mass ratio of the 2,4,6-trimethyl-1,3,5-triazine and trialdehyde phloroglucinol is preferably (0.2~0.6):(0.2~1), More preferably (0.3-0.5):(0.4-0.9), most preferably (0.4-0.45):(0.5-0.8).
[0036] In the present invention, the inorganic base is preferably potassium hydroxide and / or sodium hydroxide, and the inorganic base provides an alkaline environment for the condensation reaction. In the present invention, the molar ratio of the inorganic base to anhydrous methanol is preferably (0.1-0.6) g: (40-80) mL, more preferably (0.2-0.5) g: (50-70) mL, most preferably Preferably it is (0.35-0.4) g: (60-65) mL.

Embodiment 1
[0049]Use an electronic balance to accurately weigh 0.4318g 2,4,6-trimethyl-1,3,5-triazine (Zhengzhou Alpha Chemical Co., Ltd.), 0.7609g trialdehyde phloroglucinol (Zhengzhou Alpha Chemical Co., Ltd.) Solid and 0.3698g of potassium hydroxide, measure 60ml of anhydrous methanol with a graduated cylinder, add the medicine and reagents to a clean and dry round bottom flask, put the magnet and put the flask into a constant temperature oil bath, set up an experimental device, and make the thermometer into the silicone oil.
[0050] Turn on the power of the magnetic stirrer and the heating device, turn on the switch, and set the heating temperature to 70 °C. After condensation and reflux, the reaction was carried out for 72 hours to obtain a reaction liquid.
[0051] Turn off the magnetic stirrer and the switch of the heating device, cool the product to room temperature, filter it with suction, wash it with absolute ethanol 2 to 3 times, take a small amount in DMF (N,N-dimethylform...
