| Outline of Final Research Achievements |
High-density redox polymers with excellent charge-transport properties, based on electron self-exchange reactions in polymer layers, were employed to develop characteristic electrochemical devices for large flux charge transport and rectification at interfaces of dissimilar polymers. Capability of modulating the charge-transport properties as a function of equilibrated potentials gave rise to redox conduction properties determined by applied voltage of a gate electrode, which allowed fabrication of redox transistors. AC current amplification was accomplished with electrochemical circuits containing the redox transistor, by tuning diffusion currents based on rate constants for the exchange reaction and thickness of diffusion layers, potential gaps that dominated cross reaction at polymer/polymer heterojunctions, and molecular design of the electrochemical interfaces.
