Outline of Final Research Achievements

Mixed-conducting polymers, which conduct both ions and electrons, have potential applications in neuromimetic devices and biosensors. In order to control the properties of mixed-conductivity polymer thin films, it is necessary to understand the structure of the thin films at the molecular level, including not only the conjugated main chains responsible for electron (hole) transport but also the amorphous moieties responsible for ion transport. In this study, new spectroscopic and microscopic direct observation methods were used to clarify and establish a methodology to reveal the molecular assembly structure.
