utility of alternative solvents, three different coordination cages were dissolved in neat ionic liquids. By using 19F NMR spectroscopy to monitor the presence of free and bound guest molecules, all three cages were demonstrated to be stable and capable of encapsulating guests in ionic solution. Different cages were found to preferentially dissolve in different phases, allowing for the design of a
主客体化学反应通常在水或有机溶剂中进行。为了研究替代溶剂的效用,将三种不同的配位笼溶解在纯离子液体中。通过使用19 F NMR光谱监测游离和结合的客体分子的存在,所有三个笼子都被证明是稳定的并且能够将客体包裹在离子溶液中。发现不同的笼子优先溶解在不同的阶段,从而可以设计三相分选系统。在该系统内,三个协调笼,即Fe 4 L 6 2,Fe 8 L 12 3和Fe 4 L 4 4,每个都分成一个单独的层。在添加三种不同客人的混合物后,每个笼子(在每个单独的层中)有选择地约束其首选客人。
