在过去的二十年中，阴离子-π相互作用的研究从讨论这种反直觉键的存在到其用于阴离子识别和运输，催化和其他应用。然而，在对自然的解释和阴离子-π键的驱动力方面存在重大差异。最令人惊讶的是，关于这个术语的含义仍然有不同的意见（即，其缔合可以被认为是阴离子-π络合物）。在简要概述了这一领域的研究（包括这种络合物的早期例子）之后，我们提出，当有证据表明（闭壳层）阴离子和亲电π系统的表面之间存在净吸引力时，阴离子-π键就会发生。这个定义包含了基本相似的超分子复合物，包括不同的π系统和阴离子，它的普遍接受将有助于讨论这种迷人的相互作用的性质和独特的驱动力。
The studies of the anion‐π interactions advanced during the last two decades from the discussion of the mere existence of this counter‐intuitive bonding to its utilization for anion recognition and transport, catalysis, and other applications. Yet, there are substantial differences in the interpretation of nature and the driving forces of anion‐π bonding. Most surprisingly, there are still different opinions about the meaning of this term (i. e., which associations can be considered anion‐π complexes). After a brief overview of the studies in this area (including early examples of such complexes), we suggested that anion‐π bonding occurs when there is evidence of a net attraction between a (close‐shell) anion and the face of an electrophilic π‐system. This definition encompasses fundamentally similar supramolecular complexes comprising diverse π‐systems and anions and its general acceptance would facilitate a discussion of the nature and distinct driving forces of this fascinating interaction.
