摘要：

The electrochemistry, NMR and uv-vis spectroscopy of anthracene in ambient temperature molten salts composed of a mixture of AlCl3:1-ethyl-3-methylimidazolium chloride (ImCl) have been investigated. In acidic mixtures of AlCl3:ImCl, where the molar ratio is greater than 1, electrochemical oxidation of anthracene produces a cation radical which exhibits stability similar to that found in "super dry" dichloromethane. Electrochemical and spectroscopic measurements in the acidic melts show that anthracene protonates to form anthracenium cation. The anthracenium ion cannot be oxidized within the melt electrochemical window, but is reduced by yield H-2 and free anthracene. In basic mixtures of AlCl3:ImCl, where the molar ratio is less than 1, no anthracene electrochemistry is observed. However, NMR and uv-vis spectra in the basic melts show anthracene to be unprotonated.
