中性π-杂环自由基是一类非常重要的稳定自由基化合物。作为自旋极化的有机共轭分子，近几年来一些中性π-杂环自由基在有机导体、磁体研究方面受到很多关注，包括1，2，3，5-二噻(硒)二唑类自由基，1，3，2-二噻唑类自由基，1，2，3-二噻（硒）唑类自由基，1，2，4，6-噻（硒）三嗪类自由基，1，2，4-噻二嗪类自由基等。本文拟对一些典型杂环自由基的合成，结构等方面，特别是对其在分子导体、磁体及自旋电子材料的研究方面进行介绍。

Neutral heterocyclic π-radicals have become the most important stable radicals due to their unique structures and properties. As spin-polarized conjugated molecules, some neutral heterocyclic π-radicals have received much attention for the studies of molecular conductors and magnetic materials in recent years, including 1,2,3,5-dithia(selena)diazolyl radicals, 1,3,2-dithiazolyl radicals, 1,2,3-dithia(selena)zolyl radicals, 1,2,4,6-thia(selena)triazinyl radicals, 1,2,4-thiadiazinyl radicals. In this paper we discuss the syntheses, structures of these types of neutral heterocyclic π-radicals, particularly their potential applications as molecular conductors, magnets and spintronic materials.
