Abstract
Polycationic high-spin states of 1,3-bis(diarylamino)benzene and 1,3,5-tris(diarylamino)benzene as prototypical model units for organic ferromagnetic metals have been studied by cw and pulsed ESR spectroscopy. An electron spin transient nutation (ESTN) method as a novel technique based on pulsed ESR spectroscopy has been applied to the dicationic and tricationic high-spin states of them in glasses, unequivocally identifying the spin multiplicities of those molecules in the ground state to be triplet with the fine-structure parameters of |D| = 0.007 cm-1 and quartet with |D| = 0.004 cm-1, |E| = 0.0002 cm-1, and g = 2.0023, respectively, and concluding that the high-spin ground states originate from the topological pseudodegeneracy of the π-HOMOs which governs spin alignment in polycationic heteroatomic systems. It has been illustrated by the resolution enhancement inherent in the dimensional decomposition of 2D spectroscopy that magnetic-field-swept 2D ESTN spectroscopy is a powerful and facile method for ...
