aza-18-crown-6, 1,10-diaza-18-crown-6 and 1,4,8,12-tetraazacyclopentadecane with partially fluorinated substituents attached to nitrogen are prepared. Their efficiencies and selectivities in alkali metal and silver picrate extractions from aqueous solutions into chloroform are determined and compared with those of appropriate model compounds. Ionophores with longer spacers of –CH2OCH2CH2– and –CH2CH2OCH2CH2–
带有部分氟化物的aza-12-crown-4,aza-15-crown-5,aza-18-crown-6、1,10-diaza-18-crown-6和1,4,8,12-四氮杂环戊烷的衍生物制备与氮连接的取代基。确定了它们在从水溶液中萃取到氯仿中的碱金属和苦味酸银中的效率和选择性,并与适当的模型化合物进行了比较。在大环的氮原子和全氟烷基之间具有较长的–CH 2 OCH 2 CH 2 –和–CH 2 CH 2 OCH 2 CH 2 –间隔基的离子载体显示出比具有较短的类似物更高的萃取效率由一个或两个亚甲基组成的间隔基。
