ScholarBank@NUS Repository. https://doi.org/10.1021/ja206457b | Abstract: | 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 Å 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. © 2011 American Chemical Society. | Source Title: | Journal of the American Chemical Society | URI: | http://scholarbank.nus.edu.sg/handle/10635/76182 | ISSN: | 00027863 | DOI: | 10.1021/ja206457b |
