Problems solved by technology

[0005] The three methods mentioned above to synthesize CMPs all use heavy metals or noble metals as reaction catalysts. Although these catalysts make the catalytic activity of the reaction stronger and the reaction selectivity is better, using heavy metals or noble metals as catalysts is not only expensive. It is expensive and has extremely strict requirements on the reaction environment in the actual operation process

Embodiment 1

[0043] Use an electronic balance to accurately weigh 0.2065g 2,4,6-trimethyl-1,3,5-triazine, 0.2699g 1,3,5-benzenetricarbaldehyde and 0.3489g potassium hydroxide, and measure 60mL with a graduated cylinder Anhydrous methanol, put medicines and reagents into a clean and dry round-bottomed flask, put a magnet, put the flask into a constant temperature oil bath, set up an experimental device, and put a thermometer into the silicone oil. 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 light yellow liquid. Turn off the switch of the magnetic stirrer and the heating device, cool the product to room temperature and suction filter, wash with absolute ethanol 2 to 3 times, take a small amount in DMF (N,N-dimethylformamide) (if the solid is insoluble, then synthesize polymer), dried to obtain a white solid. Put the solid on...

Description

technical field [0001] The invention relates to the technical field of organic porous materials, in particular to a conjugated microporous polymer based on 1,3,5-benzenetricarbaldehyde and a preparation method thereof. Background technique [0002] Organic porous materials have developed rapidly in recent years. Among them, organic porous polymers (POPs) refer to a class of porous materials containing C, H, O, N and other elements with a large specific surface area and a large number of pores. It and covalent organic framework materials (COFs) are the two most important categories of organic porous materials. [0003] Organic porous polymers (POPs) can be divided into hypercrosslinked polymers (HCPs), conjugated microporous polymers (CMPs), and self-polymerizing microporous polymers (PIMs). In recent years, many porous organic polymer materials have been synthesized and applied in many fields. Among them, conjugated microporous polymers (CMPs) are mainly divided into four ...
