![عکس صفحه اول مقاله: Structures and properties of diradical compounds containing disulfide and nitroxide groups Structures and properties of diradical compounds containing disulfide and nitroxide groups](/preview/png/1440430.png)
• We prepared eight disulfide derivatives carrying a nitroxide radical.
• We elucidated the crystal structures of four derivatives by X-ray analyses.
• The structure/magnetic property relationships of the derivatives were investigated.
• The CV data of the derivatives revealed dual redox nature.
• They exhibited multi-step charge–discharge profiles with relatively large capacities.
In order to develop a kind of dual redox system with rechargeable battery property having potential high charge density, eight disulfide compounds carrying nitroxide radical have been prepared. Reflecting their multi-redox nature observed in their cyclic voltammetry data, they exhibit multi-step charge–discharge profiles with fairly large capacities over 200 Ah kg−1 for the first discharging processes. The Curie–Weiss type behaviors or 1D Heisenberg type profiles found for the respective radical compounds could be understandable by investigating the clarified crystal structures of four compounds (3, 4, 7, and 8) among them.
