Abstract
Physical and electrochemical properties are reported for SbCl3-AlCl3-N-(1-butyl)pyridinium chloride (BPC1) mixtures that are liquid at ambient temperatures, and studies of the electrogeneration and open-circuit decay of some arene radical cations, both in this medium and in SbCl3-KCl at elevated temperatures, are described. Specific conductivities, densities, and viscosities of the compositions [m/o (mole percent)] 60:19:21 (basic) and 60:21:19 (acidic) SbCl3-AlCl3-BPCl were measured over the temperature range 24°-100°C. For a potentiometric titration between the compositions 60:18:22 and 60:22:18 with SbCl3fixed at 60 m/o, the potential of the Sb(III)/Sb(0) couple increased by 0.43V at 27°C, Electrochemical studies showed that perylene (Per), 9, 10-dimethylanthracene (DMA), and 9, 10-diphenylanthracene (DPA) can be reversibly oxidized to their radical cations in a 60:19:21 melt, whereas the oxidation of anthracene (Ant) is irreversible. Spectroelectrochemical studies showed that Per radical cations were stable in this melt, those of DPA decayed very slowly, those of DMA decayed somewhat faster, and those of Ant were too transient to be observed optically. Similar degrees of stability were found for these radical cations in SbCl3containing 1M KC1 at elevated temperatures, and transient spectra of Ant radical cations were observed in this solvent. © 1984, The Electrochemical Society, Inc.
