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
