摘要
分步合成法了Schiff碱式双反应中心的功能化离子液体:首先通过1-丙胺基-3-甲基咪唑氯与FeCl3合成含有—NH2的Fe基离子液体;然后通过1,3-二氨基-2-丙醇与3,5-二叔丁基水杨醛合成Schiff碱配体H2L及其Co配合物CoL,再通过4-氯丁酰氯的酰氯基与配合物CoL的—OH反应生成含有—CH2Cl的配合物CH2Cl-CoL;最后通过Fe基离子液体的—NH2与配合物CH2Cl-CoL的—CH2Cl之间的键合反应合成Schiff碱式双功能离子液体.通过有机元素分析、红外光谱、紫外-可见光谱、核磁共振波谱、电喷雾电离质谱、电感耦合等离子体-质谱和拉曼光谱对各化合物进行了结构表征,确定Schiff碱式双功能离子液体的阳离子为Schiff碱Co络合阳离子,阴离子为Fe的络合阴离子.
Task-specific Schiff-base ionic liquid with double reactivity centers was prepared by step synthesis. Firstly, Fe-based ionic liquid with the functional group of -NH2 was synthesized by the reaction of 1-propyl- amine-3-methylimdazolium chloride and FeCI3. Secondly, Schiff-base ligand H2L was prepared by the reaction of 1,3-diamino-2-hydroxypropane and 3,5-di-tert-butylsalicylaldehyde, and its cobalt complex CoL was also prepared. Complex CH2C1-CoL with the functional group of --CH2C1 was synthesized by the reaction of 4-chlorobutyryl chloride and complex CoL. Finally, task-specific Sehiff-base ionic liquid was prepared by the reaction between --NH2 and -CH2C1 of the above two compounds. The compounds synthesized were charac- terized by elemental analysis, infrared spectrometry （ IR）, UV-Visible spectroscopy （ UV-Vis ）, 1H nuclear magnetic resonance spectra （^1n NMR）, Mass spectrometry （MS）, inductively coupled plasma mass spectro- metry （ICP-MS） and Raman spectrometry. Task-specific Sehiff-base ionic liquid was confirmed to be prepared successfully and to be composed by Schiff-base Co complex cation and Fe complex anion.
