Embodiment 1
[0013] Example 1, this example is made by the following method, the consumption of other substances is calculated according to the consumption of 1mmol of formic acid, 1mmol of formic acid and 12mmol of 2,6-diaminopyridine are placed in the reactor, and 10ml acetonitrile, disperse ultrasonically for 15 minutes to help it dissolve, and let it stand for 1 hour to make formic acid and 2,6-diaminopyridine fully act; then add 25mmol of trimethylolpropane trimethacrylate and 0.35mmol of Isobutyronitrile, after ultrasonic degassing for 10 minutes, was filled with nitrogen gas at a flow rate of 100 ml / min for 15 minutes, and the reactor was sealed after all the air was replaced by nitrogen gas. Place the reactor at room temperature under ultraviolet light to initiate polymerization for 24 hours. The polymerization product was ground and passed through a 100-mesh sieve and placed in a Soxhlet extractor, washed repeatedly for 24 hours with 150 ml of a mixture of methanol and glacial ace...
Embodiment 2
[0014] Embodiment 2, this embodiment is made by the following method, the consumption of other substances is calculated according to the consumption of 1mmol of oxalic acid, 1mmol of oxalic acid, 4mmol of acrylamide, 4mmol of 2,6-diamino Put pyridine in the reactor, add 16ml of acetonitrile and 4ml of toluene, ultrasonically disperse for 12 minutes to help it dissolve, and let it stand for 1.2 hours to make oxalic acid, acrylamide and 2,6-diaminopyridine fully act; then add 18mmol of divinylbenzene and 0.32mmol of azobisisobutyronitrile were ultrasonically degassed for 5 minutes, then filled with nitrogen at a flow rate of 120ml / min for 13 minutes, and the reactor was sealed after the nitrogen replaced all the air. The reactor was placed in a constant temperature water bath at 55°C, and the polymerization reaction was initiated for 36 hours. The polymerization reaction product is ground and placed in a Soxhlet extractor after being crossed through a 100 mesh sieve, and washed ...
Embodiment 3
[0015]Example 3, this example is made by the following method, the consumption of other substances is calculated according to the consumption of 1 mmol of formic acid, 1 mmol of formic acid and 10 mmol of acrylamide are placed in the reactor, after adding 15 ml of acetonitrile, ultrasonic Disperse for 10 minutes to help it dissolve, and let it stand for 1 hour to fully act on the template molecules and functional monomers; then add 20mmol of divinylbenzene and 0.4mmol of azobisisoheptanonitrile, and after ultrasonic degassing for 8 minutes, add 140ml The flow rate per minute was filled with nitrogen for 11 minutes, and the reactor was sealed after the nitrogen replaced all the air. The reactor was placed in a constant temperature water bath at 50°C, and the polymerization reaction was initiated for 48 hours. The product is ground and placed in a Soxhlet extractor after passing through a 100-mesh sieve, and washed repeatedly for 28 hours with a mixture of 9:1 methanol and 20% h...
