Impedance Behavior of Some Reactive Systems in Aprotic Solvents
Abstract
AC-Impedance Spectroscopic (IS) measurements in the frequency range 10 Hz ≤ f ≤ 50 kHz for some reactive systems such as diphenylanthracene (DPA), ferrocene and anthraquinone are investigated. The experiments are carried out in pure and dry dichloromethane (CH2Cl2), acetonitrile (CH3CN) and N,N- dimethylformamide (DMF) containing tetrabutylammonium perchlorate (TBAP) as supporting electrolyte. The IS diagrams of these systems are characterized in the complex plane by either straight lines passing through the origon or a high frequency capacitive and in most cases, a low-frequency Warburg behavior. The IS parameters are calculated and discussed.
