摘要:

Using the rigid 3,3-bis(4-hydroxyphenyl)-2-(4-tritylphenyl)isoindolin-1-one with polar functional groups as a building block and formaldehyde dimethyl acetal(FDA) as crossinglinker, a new hyper-crosslinked polymer (HCP) was synthesized via Friedel-Crafts alkylation reaction promoted by anhydrous FeCl3. The synthesized HCP is insoluble in boiled water and common organic solvents. Moreover, it shows a good CO2 capture capacity even if its surface area is not very high, and the absolute CO2 uptake capacity of it is 3.05 mmol/g. This can be attributed to the introduction of polar hydroxyl and lactam groups into the skeleton of the polymer, which provides effective adsorption sites for CO2. In addition, the synthesized HCP also exhibits good adsorption capacity for organic dyes in water, especially for crystal violet.
