Synthesis of 1,3-bis(diarylamino)benzenes as model precursors for one-dimensional organic ferromagnetic metals; characterization of the dications by cyclic voltammetry and electron spin transient nutation spectroscopy
A series of 1,3-bis(diarylamino)benzenes as model precursors for 1D organic ferromagnetic metals were synthesized. Cyclic voltammetric measurements showed that the corresponding monoand dication radicals with protecting groups were stable enough even at ambient temperature. A triplet state for the dication was unequivocally identified by a novel electron spin transient nutation spectroscopy.
