摘　　要：采用一步氧化偶联反应,通过1,3,5-三(9-咔唑基)-苯(TCB)自聚制备了聚合物CBPOP-1,并引入1,4-二氯苯作为连接单元与TCB通过傅克烷基化反应聚合制备了聚合物CBPOP-2,探究了连接单元的加入对有机多孔聚咔唑材料的影响。通过傅里叶-变换红外光谱(FTIR)、热重分析(TGA)以及X粉末射线衍射(PXRD)等测试手段对聚合物的结构、热性能、结晶状态以及微观形貌进行了表征和分析,利用比表面积测试仪对多孔聚合物材料的比表面积以及孔径分布进行了测定。结果表明:制备的多孔聚咔唑材料均有较高的比表面积,其中CBPOP-2的比表面积达1032 m^2/g,通过添加连接单元得到的聚合物CBPOP-2,其比表面积及热稳定性相比CBPOP-1均有所提高。A one-step oxidative coupling reaction was used to prepare the polymer CBPOP-1 by self-polymerization of 1,3,5-tris(9-carbazolyl)-benzene(TCB).And then CBPOP-2 was prepared via simple Friedel-Crafts alkylation,in which process 1,4-dichlorobenzene was introduced as a linking unit with TCB polymer.In this research,the effect of the addition of linking units on organic porous polycarbazole materials was investigated.Characterization and analysis of polymer structure,thermal properties,crystalline state,and micromorphology were performed by means of Fourier-transform infrared spectroscopy(IR),thermogravimetric analysis(TG),and X-ray diffraction(PXRD).The specific surface area and pore size distribution of the porous polymer materials were also measured.The results show that the prepared porous polycarbazole materials both have a moderate specific surface area,of which the specific surface area of CBPOP-2 reaches 1034 m^2/g.By adding the linking unit,polymer CBPOP-2 showed obvious improvement in the specific surface area and thermal stability.
