In this work, electron transfer across Au supported octadecanethiolphosphatidyl-choline (Au/ODT-PC) bilayers, which were modified with 7.7,8,8-tetracyanoquinodimethane (TCNQ). were investigated using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). Results of EIS experiments show that the TCNQ molecules act as electron conductors in the bilayer. Cyclic voltammetry indicates that the TCNQ moditied Au/thiol-lipid bilavers display strong asymmetrical conductivity in Fe(CN)₆^3/4 solution.
