阴离子-π相互作用研究进展

Research Progress on Anion-πInteractions

阴离子-π相互作用是主客体化学中的一种非共价引力相互作用.通常,芳香族π-系统被认为是富电子的,可能与负电荷体系间存在排斥作用.因此,看似违反常理的阴离子-π相互作用,自其首次被报道就受到了高度关注,并迅速在分子识别、催化、自组装、聚集诱导发光材料和新型阴离子受体设计合成等领域展现出了广阔而重要的应用前景.综述了近10年阴离子-π相互作用在理论计算研究、催化、自组装、受体设计与合成、聚集诱导发光等领域的研究进展,并对于阴离子-π相互作用在超分子化学领域中的研究与应用进行展望,为超分子化学研究提供参考.

Anion-πinteraction is a non-covalent interaction in host-guest chemistry.In general,aromaticπ-systems are regarded as electron rich and may have repulsive interactions with negatively charged systems.Therefore,the anion-πinteraction,which seems counterintuitive,has attracted remarkable attention since it was first reported.And surprisingly,it has shown broad and significant potential applications in various fields,including molecular recognition,catalysis,self-assembly,aggregation-induced luminescent materials,and the design and synthesis of novel anionic receptors.This review focuses on the research progress of anion-πinteractions in the fields of theoretical studies,catalysis,self-assembly,receptor design and synthesis,and aggregation-induced luminescence in the last decade.Finally,the research and application prospects of anion-πinteractions in the field of supramolecular chemistry will be provided.
