The electrochemical and spectroscopic properties of a new family of stable radical cations based on 2(3H)-thiazolone azine were investigated. All of the studied compounds display two redox processes, leading to a radical cation, and then to a dication, the radical mono-cation being intensely blue-colored. These properties suggest that this new family of dyes provides excellent candidates for electrochromic devices, such as electrochromic windows, or as redox indicators or mediators.
研究了基于 2(3H)-thiazolone azine 的新型稳定自由基阳离子家族的电化学和光谱特性。所研究的所有化合物都显示出两个氧化还原过程,先生成一个自由基阳离子,然后生成一个二阳离子,自由基单阳离子呈现出强烈的蓝色。这些特性表明,这一新的染料家族是电致变色设备(如电致变色窗)或氧化还原指示剂或调解剂的绝佳候选材料。
