| Outline of Final Research Achievements |
We proposed the combination of "charge-storage" based on redox reaction of durable organic radicals (SOMO) and "charge-conduction" through π-conjugation (HOMO-LUMO) to yield new energy-storage materials. Especially, we focused on vapor-phase oxidative polymerization (VPP) as a facile method for in-situ preparation of π-conjugated polymers. Prior to VPP process, chemical oxidants such as Fe(OTs)3 were mixed with nitroxide radical polymers to convert the corresponding oxoammonium salts, to suppress the radical inhibition of oxidative polymerization of EDOT. The obtained p- and n-type radical polymers/PEDOT blend was utilized as cathode- and anode-active materials, respectively, leading to the metal-free, wearable rechargeable battery. In-situ VPP method using oxidant vapors such as iodine also produced organic donor layer toward organic solar cells.
