摘　　要：以N-甲基咪唑和溴乙醛缩二乙醇,经亲核取代反应合成1-乙醛基缩二乙醇-3-甲基咪唑溴化物离子液体([ADDMIM]Br),并利用盐酸对该离子液体进行酸化,制备1-乙醛基-3甲基咪唑溴化物离子液体([ADMIM]Br)。最后以刚性的苯/氨基封端的苯胺四聚体和柔性的离子液体为基体,反应得到苯胺四聚体与离子液体的刚柔嵌段共聚物(RBCATII)。采用红外光谱(FTIR)、核磁共振仪(^(1)H NMR)和元素分析对其进行结构与性能测试与分析。结果表明,实验成功制备出1-乙醛基缩二乙醇-3-甲基咪唑溴化物和1-乙醛基-3-甲基咪唑溴化物离子液体、苯胺四聚体,并且合成了1-乙醛基-3-甲基咪唑溴化物离子液体和苯胺四聚体的嵌段共聚物。1-Acetaldehyde diethanol-3-methylimidazole bromide([ADDMIM]Br)was synthesized by nucleophilic sub-stitution reaction of N-methylimidazole and bro-moacetaldehyde diethyl acetal.Functional aldehyde based ionic liquids 1-acetaldehyde-3-methylimidazolium bromide([ADMIM]Br)was prepared by[ADDMIM]Br acidified with hydrochloric acid.Finally,Rod-coil block copolymers of aniline tetramers and ionic liquids(RBCATII)were prepared by the reaction of rigid benzene/amino terminated aniline tetramers and flexible ionic liquids.The structure was characterized by FTIR,^(1)H NMR and elemental analysis.The results show that[ADMIM]Br,[ADDMIM]Br,(RBCATII)was successfully prepared.
