Electrode properties of TCNQ (7,7,8,8-tetracyanoquinodimethane) and BEDT-TTF (bis- (ethylenedithio)tetrathiafulvalene) derivatives are considered. The BEDT-TTF-based organic electrode materials were produced by electrochemical technique. Electrodes with TCNQ salts were obtained by thermal or evaporation method. Polarization and impedance investigations have shown the high electrode activity of the BEDT-TTF based materials in irreversible electrochemical processes. TCNQ-based OM sensitivity to pH as well as electrode surface resistance vary depending on gaseous phase composition. The latter circumstance is quite prospective for applications of organic metals in analytical control devices.
