In this study, we explorethe synthesis of binaphthyl-based chiral macrocyclic hosts for the first time. They exhibited the selective recognition abilities of iodide anions which can be favored over those of other anions (AcO, NO, ClO, HSO, Br, PF, HPO, BF, and COFS), as confirmed by UV-vis, HRMS, and H NMR spectroscopy experiments, as well as DFT calculations. Neutral aryl C-H···anion interactions play an important role in the formation complexes. The recognition process can be observed by the naked eye.
在这项研究中，我们首次探索了基于联萘的手性大环主体的合成。通过紫外-可见、高分辨率质谱和核磁共振波谱实验以及密度泛函理论计算证实，它们对碘离子具有选择性识别能力，可以优先于其他阴离子（AcO、NO、ClO、HSO、Br、PF、HPO、BF 和 COFS）。中性芳基 C-H···阴离子相互作用在形成配合物中起着重要作用。识别过程可以用肉眼观察到。
