Abstract
Polycationic high-spin states of star-burst molecules based on (diaryl amino)benzenes have been studied by cw and pulsed ESR spectroscopy. An electron spin transient nutation (ESTN) method based on pulsed ESR sp ectroscopy was applied to the dicationic and tricationic high-spin sta tes of N,N,N',N'-tetra(4- anisyl)-2,4-dimethyl-1,5-phenylenediamine an d ',N',N'',N''-hexa(4-anisyl)-1,3,5-triaminobenzene, respectively, in order to identify the spin multiplicity of the polycationic states. Th e observed 2D nutation spectra of the dicationic and tricationic state s unequivocally showed that the dicationic and tricationic states are ground-state triplet and quartet, respectively.
