Voltammetric, electrochemical quartz crystal microbalance and in situ conductance studies of conducting polymers based on ethylenedioxythiophene and N-ethylcarbazole

Previous electrochemical studies on the redox transformation of 3,6 bis(3,4-ethylenedioxythiophenyl)-9-ethylcarbazole (Ed-ECz-Ed) have been completed by further electrochemical, electrochemical quartz crystal microbalance (EQCM) and in situ conductance measurements. Effect of electrode gap for in situ conductivity measurements, cycle number and potential range were investigated. The EQCM measurements results showed the conductance in the n-doping range and conductivities were high enough to use the 20 μm microarray electrodes.
