【摘要】 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)三嗪类自由基和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。更多还原

【Abstract】 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.更多还原
