报告摘要：We have focused on aliphatic polymers bearing redox-active groups per repeating unit. The redox polymers are characterized by an ultimate population of the electron-releasing and -gaining site that allows efficient redox-driven electron- or charge-transport and -storage throughout the polymer layers via self-exchange reactions. Challenges toward paper-like and bendable rechargeable batteries by molecular designing of the redox polymers will be demonstrated. We are also fabricating dye-sensitized photovoltaic cells with the redox polymer layers for charge-separation and -transport in the cell. The cells displayed significantly high voltage of almost 1 V, which are being tested as a cord-less power source assisted with interior lighting.

Another example is anode-active redox polymers which reversibly formed their hydrogen additives. The redox polymer resins are being examined as a new-type hydrogen carrier, of which advantages are non-explosive, non-leakage, safety transportation, storage, and facile evolution of hydrogen. Redox polymers are emerging as a new class of organic materials for energy-storage and -conversion devices.
