Embodiment 1
[0042] At normal temperature and pressure, add pyrrole (0.2ml) and chloroform (20ml) into a 100ml Erlenmeyer flask and mix thoroughly, add ferric chloride (2901mg) and nitromethane (20ml) into another small beaker, mix and dissolve . Afterwards, keep the Erlenmeyer flask with pyrrole and chloroform at 20°C under a water bath and stir it, add the mixed solution of ferric chloride and nitromethane dropwise (1-5 drops / 5 minutes), and cover it after adding The glass stopper was sealed and reacted for 24 hours, then anhydrous methanol (50ml) was added and stirring was continued for 1 hour. Purify after the reaction, extract with methanol for 24 hours, then extract with chloroform for 24 hours, and finally dry in vacuum at 60°C for 24 hours to obtain pyrrolyl conjugated microporous polymer powder with a specific surface area of 739m 2 / g, for CO at 273K, 1.0bar and 298K, 1.0bar 2 Adsorption reached 9.6 wt% and 5.6 wt%, respectively.
