  Five-Fold-Symmetric Macrocyclic Aromatic Pentamers: High-Affinity Cation Recognition, Ion-Pair-Induced Columnar Stacking, and Nanofibrillation

  摘要：

  Described in this study is a conceptually new class of five-fold-symmetric cavity-containing planar pentameric macrocycles with their interior decorated by five convergently aligned, properly spaced carbonyl oxygen atoms. These cation-binding oxygens enclose a hydrophilic lumen of 2.85 angstrom in radius and thus display high-affinity binding toward alkali metal cations, and possibly many other cations, too. Arising from their high-affinity recognition of metal ions, these planar macrocycles form cation- or ion-pair-induced one-dimensional columnar aggregates, and subsequently fascinating fibrillation results.

  well over 22 other metal ions. Despite the lack of sulfur atoms and having only oxygen-donor atoms in its structure, the best foldarand molecule, i.e., tetramer 4, exhibits a selectivity factor of at least 19 in differentiating the most tightly bound Hg2+ ion from all other metal ions, and a binding capacity that is ≥18 times that of thio-crown ethers. These two noteworthy binding characters make possible

  在没有大环限制的情况下，很少有合成系统具有主要与溶剂无关的折叠构象，易于对金属离子进行高选择性和高亲和力识别。我们在这里报告了这样一类独特的构象鲁棒性模块化可调折叠分子，称为折叠分子，它可以识别 Hg2+ 离子，比其他 22 种金属离子出奇地好。尽管缺乏硫原子并且其结构中只有氧供体原子，但最好的折叠分子，即四聚体 4，在区分最紧密结合的 Hg2+ 离子与所有其他金属离子方面表现出至少 19 的选择性因子，并且结合能力≥硫冠醚的18倍。这两个值得注意的结合特征使 Hg2+ 离子的低水平去除成为可能。随着 [4]：[Hg2+] 摩尔比为 5:1 和单相双相溶剂萃取，纯水中的 Hg2+ 离子浓度可大幅降低 98%（从 200 到 4 ppb）。4 还可以通过多次连续提取将人工地下水中的汞含量高效降低 98%（从 500 到 10 ppb），总消耗量为 4，即 [4]:[Hg2+] 摩尔比为 9:1
