characterized by varied ion–dipole interactions with lithium, culminating in significantly enhanced binding affinity and Li+/Na+ selectivity compared to conventional macrocyclic crown ether-based receptors. Moreover, we identify a new building block based on pyridine-N-oxide, which serves as an efficacious motif for developing receptors with augmented lithium-binding capacities. Additionally, our findings demonstrate
各个行业对锂的需求不断增长,尤其是在锂离子电池领域,因此需要开发高效的提取和纯化方法。作为对这一势在必行的回应,设计对锂离子具有高选择性和亲和力的合成受体已成为一个重要的研究领域。本研究提出了一种简单有效的高性能锂受体方法,该方法利用离子偶极相互作用作为锂结合的主要驱动力。我们的研究包括设计、合成和评估五种不同的离子载体,其特征是与锂的离子-偶极相互作用不同,最终显着增强了结合亲和力和 Li + /Na +与传统的基于大环冠醚的受体相比具有选择性。此外,我们确定了一种基于吡啶-N-氧化物的新结构单元,它可作为开发具有增强锂结合能力的受体的有效基序。此外,我们的研究结果表明,在大量过量的 NaCl 和 KCl 存在的情况下,使用新发现的离子载体可以快速有效地固液萃取 LiCl。总的来说,这项研究为高性能锂受体的分子设计策略提供了宝贵的见解,并倡导继续探索可持续的分子材料以提高锂的识别和提取效率。
