Two or more anions constrained in close proximity within a single pocket are found in a number of natural systems but are a less common motif in artificial systems. This review summarizes work on anion receptors capable of stabilizing anionic dimers, trimers, tetramers, and clusters in a well-defined fashion. These systems could provide insights into the fundamental chemistry of anion-anion interactions and provide a guide for understanding a number of biological and environmental processes in greater detail, as well as key tenants of relevance to supramolecular chemistry, extraction, transport, crystal engineering, and the like. The primary goal of this review is to provide a general introduction to multi-anion recognition chemistry for the benefit of supramolecular and non-supramolecular chemists alike.

在许多自然系统中都发现了两个或多个阴离子被限制在一个口袋内，但在人工系统中却不太常见。这篇综述总结了能够以明确的方式稳定阴离子二聚体、三聚体、四聚体和簇的阴离子受体的工作。这些系统可以深入了解阴离子-阴离子相互作用的基本化学，并为更详细地理解许多生物和环境过程以及与超分子化学、提取、运输、晶体工程和相关的关键租户提供指导。之类的。本综述的主要目标是提供多阴离子识别化学的一般介绍，以造福超分子和非超分子化学家。
