The thiosemicarbazide derivative of anthracene, ATSC, has been synthesized and characterized by elemental analysis, IR, UV-visible, (1)H NMR, fluorescence, and mass spectroscopy experiments. The interaction of hydrated electron (e(-)aq) with ATSC proceeds via radical anion formation followed by intramolecular transfer that cleaves the thiosemicarbazide side chain on the anthracene moiety. HPLC and ESI-MS experiments suggested that the anthrylmethyl radical combines with different ATSC fragments during the reaction. ATSC, its one-electron reduction products, and dimers were analyzed combining experiments with density functional theory.
