Abstract

Anion-π interaction, i.e., the attraction between anions and electron-deficient π systems, is a newly recognized non-covalent interaction. Since the pioneering theoretical prediction and nomination, recent years have witnessed the remarkable applications of this non-covalent driving force in anion recognition, sensing, ion transport, and catalysis. Relatively, utilizing anion-π to direct molecular self-assembly remains largely unexplored. This is not surprising as anion-π depending on the nature and shape of anions shows versatile binding geometries. The versatile geometries result in reduced directionality and increased difficulty on rational design of self-assembly. This challenge could be overcome through cooperating anion-π with other non-covalent interactions, and/or rationally designing the organic and anionic building units to maximize the strength and to confine the directionality of anion-π interactions. In this review, we focus on the achievement of self-assemblies dominated by anion-π interactions. Three main topics are involved: self-assembly with (1) anion as template, (2) anions as primary building units, and (3) anions as secondary building units.
