Embodiment 1
[0024] At room temperature, add 20ml of 1,2-dichloroethane, 1.56g of benzene and 4.56g of dimethoxymethane into a three-necked flask equipped with a reflux condenser and a thermometer, and stir magnetically for 0.2 hours. Then add 6.50 g of anhydrous ferric chloride, raise the temperature to 45° C., stir magnetically at this temperature for 5 hours, then raise the temperature to 80° C., and stir magnetically at this temperature for 18 hours. During the above process, magnetic stirring was maintained. The reaction product was filtered to obtain a brown solid crude product, which was washed three times with ether and methanol, and then extracted with methanol in a Soxhlet extractor for 24 hours. Finally dry under reduced pressure to obtain the porous polymer material, its infrared spectrum is shown in the attached figure 1 , at 1600cm -1 , 1500cm -1 and 1450cm -1 The infrared peaks prove that the porous polymer has an aromatic ring structure; 13 C solid NMR spectrum see att...
Embodiment 2
[0026] At room temperature, add 20ml of 1,2-dichloroethane, 3.08g of biphenyl and 3.04g of dimethoxymethane into a three-necked flask equipped with a reflux condenser and a thermometer, and stir magnetically for 0.5 hours. Then add 6.50 g of anhydrous ferric chloride, raise the temperature to 45° C., stir magnetically at this temperature for 5 hours, then raise the temperature to 80° C., and stir magnetically at this temperature for 18 hours. During the above process, magnetic stirring was maintained. The reaction product was filtered to obtain a brown solid crude product, which was washed three times with ether and methanol, and then extracted with methanol in a Soxhlet extractor for 24 hours. Finally dry under reduced pressure to obtain the porous polymer material, its infrared spectrum is shown in the attached image 3 , at 1600cm -1 , 1500cm -1 and 1450cm -1 The infrared peaks prove that the porous polymer has an aromatic ring structure;13 C solid NMR spectrum see atta...
Embodiment 3
[0028] At room temperature, add 20ml of 1,2-dichloroethane, 1.86g of toluene and 3.04g of chloromethyl methyl ether into a three-neck flask equipped with a reflux condenser and a thermometer, and stir magnetically for 0.5 hours. Then add 6.50 g of anhydrous ferric chloride, raise the temperature to 45° C., stir magnetically at this temperature for 5 hours, then raise the temperature to 80° C., and stir magnetically at this temperature for 18 hours. During the above process, magnetic stirring was maintained. The reaction product was filtered to obtain a brown solid crude product, which was washed three times with ether and methanol, and then extracted with methanol in a Soxhlet extractor for 24 hours. Finally dry under reduced pressure to obtain the porous polymer material, its infrared spectrum is shown in the attached Figure 5 , at 1600cm -1 , 1500cm -1 and 1450cm -1 The infrared peaks prove that the porous polymer has an aromatic ring structure; 13 C solid NMR spectrum...
