Porous liquids (PLs) are a novel material that combines the advantages of porous solids and liquid fluidity. In this study, we propose an imprinted porous liquid (IPL) with imprinted polymers as the porous framework and a mixture of TOP + FeCl₃ as sterically hindered solvents. Quantum chemical computations and characterization results demonstrate the presence of unoccupied pore structure in IPLs. The prepared IPLs exhibit excellent selective adsorption and extraction performance for lithium extraction, achieving a Li/Mg separation factor of 1540 and a single-stage Li⁺ extraction efficiency of 86%. The Li⁺ extraction efficiency remains above 84% even after eight cycles. Analytical characterization along with quantum chemical computations elucidates the mechanism underlying the coupling between extraction and adsorption in IPLs, enabling efficient lithium extraction. By combining imprinting technology with PLs, IPLs expand upon existing frameworks for PLs materials while providing new insights for designing functional solvents.

一种用于锂提取的新型压印多孔液体


多孔液体 （PLs） 是一种结合了多孔固体和液体流动性优点的新型材料。在这项研究中，我们提出了一种印迹多孔液体 （IPL），以印迹聚合物作为多孔框架，并以 TOP + FeCl₃ 的混合物作为空间阻阻溶剂。量子化学计算和表征结果表明 IPL 中存在未占据的孔结构。所制备的 IPL 表现出优异的锂提取选择性吸附和提取性能，Li/Mg 分离因子为 1540，单级 Li⁺ 提取效率为 86%。即使在 8 次循环后，Li⁺ 提取效率仍保持在 84% 以上。分析表征以及量子化学计算阐明了 IPL 中萃取和吸附之间耦合的潜在机制，从而实现高效的锂提取。通过将压印技术与 PL 相结合，IPL 扩展了 PL 材料的现有框架，同时为设计功能性溶剂提供了新的见解。
