摘要: 反芳香体系是一类因π电子的离域导致能量升高、稳定性下降的化合物,通常具有窄HOMO-LUMO能隙、顺磁环电流等特性,在光、电、磁等领域展现出潜在应用价值。本文简介了反芳香性的概念,探讨了五类典型反芳香体系的结构与性质,扩充了本科经典教材中较少涉及的反芳香化合物相关内容,有助于充实学生芳香化学领域的知识储备。

Abstract: Antiaromatic systems are a class of compounds where the delocalization of π electrons results in an increase in system energy and a decrease in stability. Antiaromatic compounds typically exhibit distinctive features including narrow HOMO-LUMO gaps and paramagnetic ring currents, holding considerable potential applications in fields such as optics, electronics, and magnetism. This article introduces the concept of antiaromaticity and discusses the structures and properties of five representative types of antiaromatic compounds, which enriches the relatively sparse discourse on antiaromatic compounds present in traditional undergraduate textbooks, thereby contributing to enhancing students’ knowledge on aromatic chemistry.

Key words: π Electron, Antiaromaticity, Organic synthesis
