4,8-Dialkylbenzo[1,2-d:4,5-d’]bis[1,2,3]triselenoles [alkyl = Et, Bu, and Oc (C8H17)] were first prepared and treated with concentrated sulfuric acid-d2 to generate benzobistriselenole dications, which were determined by NMR spectroscopy. The oxidation of dioctylbenzobistriselenole with three equivalents of single-electron oxidizing reagent (NOSbF6) produced the corresponding dication•2SbF6–, and the salt was isolated into a stable form. The ESR spectra of the dications measured in concentrated sulfuric acid in the range of room temperature and –196 °C were observed as split peaks similar to that of solid state dication•2SbF6–. Magnetic susceptibility of the dication•2SbF6– was determined by a SQUID magnetometer, which showed the salt is diamagnetic. The optimized structures and the total energy of the singlet- and triplet-state benzobistriselenole dications were calculated using the DFT method at the B3LYP6-311G**(d,p) level. The results revealed that the structures of the singlet- and triplet-state dications calculated have a completely planar forms and the triplet-state dication is slightly more stable than the singlet-state one (in acetonitrile, PCM).
