Abstract: The invention demonstrates the synthesis of a new pyrazole-containing monomer by means of an easily implemented two-step process. This monomer can be electropolymerized to yield a stable n-doping polymer that may easily be electrochemically characterized. It is demonstrated that the electrochemical behavior of the polymer films produced is dependent upon the conditions applied during electrodeposition. Films deposited by cycling only at relatively positive potentials (0 to 2000 mV) show less intense n-doping responses than those films obtained by scanning the applied potential throughout a wider range (?2000 mV to 2000 mV).
