Electrochemical and Spectroscopy Studies of Selected Inorganic and Organic Systems in Molten Halides
Abstract
The research during the past year has concentrated on the photochemistry of anthracene and 9-methylanthracene in molten aluminum chloride- 1-ethyl-3-methylimidazolium chloride (AlCl3/EMIC), looking in particular for photoinduced electron transfer reactions. Several such reactions have been found. Experiments demonstrate that this chemistry was initiated by electron transfer from the excited state of 9-methylanthracene to EMI+. The difference in behavior of anthracene and 9-methylanthracene in the basic melt can be attributed to the difference in the rate of electron transfer to EMI+: for anthracene, the electron transfer is endothermic and slow, while for 9- methylanthracene, the electron transfer is exothermic and fast. Irradiation of anthracene in oxygenated basic medium afforded several products including 9- chloranthracene. Although the formation of 9-chloranthracene can be envisioned to arise by electron transfer from the excited state of anthracene to O2, additional work will be required to prove that this assumption is correct
