Self-doped conductive polymers of ferrocene were synthesized and characterized. The polymers were prepared via Suzuki-Miyaura coupling reaction in biphasic mixture ofo-xylene and sodium carbonate solution at 180 oC. Chemical structures of the polymers were identified using several spectroscopic techniques including FTIR, C13- and H1- NMR. The electrochemical behaviors were investigated by cyclic voltammetry at ambient temperature in reference to Ag/Ag+. Electrical conductivities of the polymers were examined for metal-polymer-metal (MPM) film structure, and the measurements showed 1.0x10-5 to 1.0x10-4 S/cm. The current-voltage (I-V) characteristics were studied on both single-layer and bi-layer films with Poly(3,4-ethylenedioxythiophene). I-V results indicated non-ohmic behaviors, and resistance switching from low-conductance state to high-conductance state was observed in bi-layer MPM devices. |
