π-π作用是芳环超分子体系中广泛存在的一种重要的弱相互作用.本文对π-π作用的特征、形式、有效参数和表征方法等作了比较全面的综述,同时小结了影响π-π作用的一些重要因素,最后还概述了近年来π-π作用在超分子组装、不对称催化、有机半导体材料等领域的研究进展.
π-π interaction, as an important weak interaction, extensively exists in an aromatic supramolecular system. The characters, types, valid parameters, examinable methods and influence factors are summa- rized for π-π interaction. In addition, some introduction is made for evolution of π-π interaction in the field of self-assembly, asymmetric catalysis, organic semiconductor, and so on.
