Novel spin-polarized TTF donors affording ground state triplet cation diradicals

The concept of “spin-polarized” donor was successfully extended to TTF-based donor radicals. A series of TTF derivatives carrying a phenyl nitronyl nitroxide group were prepared, and they turned out to afford ground state triplet cation diradicals through one-electron oxidation. Such “spin-polarized...

Summary:The concept of “spin-polarized” donor was successfully extended to TTF-based donor radicals. A series of TTF derivatives carrying a phenyl nitronyl nitroxide group were prepared, and they turned out to afford ground state triplet cation diradicals through one-electron oxidation. Such “spin-polarized” TTF donors are expected to become building blocks for organic conducting ferromagnets. One-electron oxidation of TTF-based donor radicals (1–4) was proved to afford ground state triplet cation dicadicals.
