Outline of Final Research Achievements |
Dicationic heteroacenes that bear thio- or selenopyrylium moieties were synthesized by addition reactions of the corresponding diones with a Grignard reagent, followed by a dehydration reaction of the resulting diols with Brensted acid. Alternatively, these dicationic heteroacenes were obtained from two-electron oxidations of the corresponding sulfur- or selenium-containing quinoids. The electronic structures of these heteroacenes were examined by NMR and UV-vis-NIR spectroscopy in conjunction with density functional theory calculations. The results of this combined experimental and theoretical approach strongly imply effective conjugation of 22pi-electrons in a system that is distributed over the entire pentacene framework.
