| titleOfInvention | L-tartaric acid modified self-made microporous polymer membrane and preparation method thereof |
| abstract | The invention relates to an L-tartaric acid modified self-micropore polymer membrane and a preparation method thereof, which comprises the steps of firstly transferring N, N-dimethylformamide into a dry three-neck flask, then transferring 5,5 ', 6,6 ' -tetrahydroxy-3, 3,3 ', 3 ' -tetramethyl-1, 1 ' -spiral bisindane and 3,4,5, 6-tetrafluoro phthalonitrile into the three-neck flask, stirring until the two components are dissolved, and then adding anhydrous potassium carbonate and L-tartaric acid; vacuumizing the heterogeneous mixture, introducing nitrogen for protection, heating and stirring; cooling to room temperature, adding deionized water into the flask, performing suction filtration to obtain yellow precipitate, and performing multiple rinsing with water and methanol respectively; finally, vacuum drying the obtained product; dissolving the product with tetrahydrofuran, and pouring the product into a quartz culture dish with the diameter of 6cm at room temperature to prepare a membrane; the polymer film of the invention is introduced with L-tartaric acid, so that the film has chiral characteristics, and thus has chiral recognition capability. |
