【摘要】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 FeCl3. 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 CH2Cl-CoL with the functional group of —CH2C1 was synthesized by the reaction of 4-chlorobutyryl chloride and complex CoL. Finally, task-specific Schiff-base ionic liquid was prepared by the reaction between —NH2 and —CH2C1 of the above two compounds. The compounds synthesized were characterized by elemental analysis, infrared spectrometry (IR ) , UV-Visible spectroscopy ( UV-Vis ) ,
1H nuclear magnetic resonance spectra ( 1 H NMR) , Mass spectrometry ( MS) , inductively coupled plasma mass spectrometry (ICP-MS) and Raman spectrometry. Task-specific Schiff-base ionic liquid was confirmed to be prepared successfully and to be composed by Schiff-base Co complex cation and Fe complex anion.%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.
