| Outline of Final Research Achievements |
The present study was performed with the aim of fundamental understanding of the charge transport and storage processes in amorphous polymers with densely substituted charge-transfer sites that exhibit electrochemical reversibility. The research also aimed at deriving a generalized concept of redox bistability of polymers.
Specifically, we have organized chemical structures applicable as charge transfer sites and synthesized polymers with small equivalent weights (i.e. high density in monomer units). We also showed that the charge transport efficiency is enhanced by using molecular-level composite electrodes incorporating π-conjugated systems. Based on these findings, we have developed various examples of redox-bistable polymers such as potential-driven mediators that enable high-density charge storage and fast charging, and established them as a group of functional polymers characterized by redox bistability.
