The polarographic behavior of 9-nitroanthracene and 9,10-dinitroanthracene has been studied in dimethylformamide. 9-Nitroanthracene shows consecutive two one-electron diffusion-controlled reduction waves followed by fast chemical reactions. 9,10-Dinitroanthracene, however, shows only one reversible two-electron diffusion-controlled wave. The effect of the supporting electrolyte cation on these reduction waves was also investigated. In alkali metal or alkaline earth metal perchlorate as a supporting electrolyte, the half-wave potentials shift to the anodic side. The relationship between the half-wave potential and the ionic potential of the cation was discussed.
