The EPR properties of novel nitroxide-spin-labelled rotaxanes containing a tetrathiafulvalene (TTF) unit and a cyclobis(paraquat-p-phenylene) ring are described. The rotaxanes were spin labelled both at the thread and the wheel. Single-electron oxidation of the TTF unit resulted in a significant through-space magnetic interaction between different radical units. In some cases, rotaxanation is proved to have dramatic effects on such magnetic interactions.

描述了含有四硫富瓦烯（TTF）单元和环双（百草枯-对苯撑）环的新型硝基氧化物旋转标记的轮烷的EPR性质。轮烷在螺纹和转轮上均被旋转标记。TTF单元的单电子氧化导致不同自由基单元之间发生明显的贯穿空间的磁性相互作用。在某些情况下，证明轮烷化对这种磁性相互作用具有显着影响。
