The selective separation of structurally similar aliphatic/aromatic hydrocarbons is an essential goal in industrial processes. In this study, we report the synthesis of a water-soluble (TrM)L (Tr = cycloheptatrienyl ring; M = metal; L = organosulfur ligand) molecular cage () via self-assembly of the water-soluble acceptor tripalladium sandwich species [(TrPd)(CHCN)][NO] and the attachment onto L of solubilizing methoxyethoxy appendants to be utilized in an energy-friendly alternative approach to the separation of structurally similar molecules under ambient conditions. Cage , comprising a hydrophobic inner cavity, exhibited good solubility and stability in aqueous media. It also demonstrated excellent performance in the sequential separation of alkanes (C6-C9), xylene, and other disubstituted benzene isomers and /-decalin.
选择性分离结构相似的脂肪族/芳香族烃类是工业过程中的一个重要目标。在这项研究中，我们报告了一种水溶性（TrM）L（Tr = 环庚三烯基环；M = 金属；L = 有机硫配体）分子笼（）的合成，该分子笼通过水溶性受体三钯夹心物种[(TrPd)(CHCN)][NO]的自组装和在 L 上附着可溶的甲氧基乙氧基附加物来实现，可用于在环境条件下以节能的方式分离结构相似的分子。包含疏水内腔的笼，在水介质中表现出良好的溶解性和稳定性。它还在烷烃（C6-C9）、二甲苯和其他二取代苯异构体和 /-十氢萘的顺序分离中表现出优异的性能。
