设计合成了醛基或酮基功能化的咔唑9-(4-联苯) -3-甲醛基咔唑(CM-2)、9-(4-联苯) -4-乙酮基咔唑(CM-3)和9-(4-联苯) -2,6-二氟-3-乙酮基咔唑(CM-4).分别以CM-2,CM-3和CM-4为单体,以FeCl_3为催化剂,采用一步法制备了超交联多孔聚咔唑:聚[9-(4-联苯) -3-甲醛基咔唑](HPP-2)、聚[9-(4-联苯) -4-乙酮基咔唑](HPP-3)和聚[9-(4-联苯) -2,6-二氟-3-乙酮基咔唑](HPP-4).反应中间体和聚咔唑的结构由核磁共振波谱(~1H NMR,~(13)C NMR)、魔角旋转交叉固体核磁共振波谱(~(13)C CP/MAS NMR)、红外光谱(IR)和质谱(MS)进行表征,研究了聚咔唑的热稳定性及气体(氮气、二氧化碳和甲烷)吸附性能.结果表明,3种聚咔唑...

Three novel carbazoles CM-2, CM-3 and CM-4 were designed and synthesized by ketone- or aldehyde-functionalization of carbazole. Then a series of hypercrosslinked porous polycarbazoles(HPP-2, HPP-3 and HPP-4) was prepared using CM-2, CM-3 and CM-4 as monomers under the catalysis of FeCl 3 . The structures of the novel carbazoles and the hypercrosslinked porous polycarbazoles(HPPs) were characterized by nuclear magnetic resonance( 1 H NMR, 13 C NMR), magic angle spinning nuclear magnetic resonance(MAS NMR), infrared(IR) and mass spectrometry(MS)....
