Using anions to induce molecular structure is a rapidly growing area of dynamic and switchable supramolecular chemistry. The emphasis of this review is on helical anion foldamers in solution, and many of the beautiful complexes described herein are accentuated by their crystal structures. Anion foldamers are defined as single- or multistrand complexes-often helical-that incorporate one or more anions. The review begins by discussing foldamer structure and nomenclature and follows with discourse on the anions which are employed. Recent advances in functional foldamers that bind a single anion are examined, including: induced chirality, stimuli-responsive dynamics, fluorescence changes, organocatalysis, anion transport, and halogen bonding. The review then inspects multianion foldamers, and this section is organized by the number of strands within the foldamer-from single- to triple-strand foldamers. Finally, the review is punctuated by recent hydrogen- and halogen-bonding triple-strand anion foldamers.

溶液中的螺旋阴离子折叠剂。

使用阴离子诱导分子结构是动态且可切换的超分子化学的快速增长领域。这篇综述的重点是溶液中的螺旋阴离子折叠剂，并且本文所述的许多美丽的配合物的晶体结构也突显了它们。阴离子折叠剂定义为掺入一种或多种阴离子的单链或多链络合物（通常为螺旋形）。本文首先讨论折叠结构和命名，然后讨论所用阴离子。研究了结合单个阴离子的功能性折叠剂的最新进展，包括：诱导的手性，刺激响应动力学，荧光变化，有机催化，阴离子运输和卤素键。然后，审核人员检查多阴离子折叠剂，并且此部分由折叠夹中的链数（从单链到三链折叠器）组成。最后，该评论被最近的氢键和卤素键三链阴离子折叠剂打断。
