与氯代芳族化合物(dCl <$Cl <$4.0 <$)相关的β-折叠结构已被实现以驱动二噻二唑基自由基的π-堆叠结构的形成。这两个标题化合物表现出增加在150 K以上的顺磁性,但固态EPR研究表明,在这两个系统中的顺磁性的起源是不同的。
The β-sheet structure associated with chlorinated aromatics (dCl⋯Cl ≈ 4.0 Å) has been implemented to drive formation of π-stacked structures of dithiadiazolyl radicals. Both title compounds exhibit an increase in paramagnetism above 150 K but solid-state EPR studies indicate that the origin of the paramagnetism in these two systems is different.
