| Outline of Final Research Achievements |
Oxygen is a reactive species in various energy conversion devices. The oxygen concentration in the air is about 21%, and once it can be increased, chemical reactions can be promoted. However, the concentration of substances is a process that consumes a lot of energy, although in the natural world, separation/concentration and transport of oxygen molecules are realized with low energy consumption, such as oxygen transport in the blood. Therefore, in this study, we focus on oxygen binding behaviors of metal porphyrin complexes in solution and examine its electrochemical response associated with oxygen binding.

酸素は，様々なエネルギー変換デバイスにおける反応化学種である．酸素の空気中濃度は約21%であるが，これを高めることができれば，化学反応を促進することが可能となる．本研究では，血液中の酸素運搬から着想し，低エネルギー消費での酸素分子の分離・濃縮と輸送の実現に向けて，溶液中の金属ポルフィリン錯体への酸素分子の配位結合に着目した研究を実施した．酸素または窒素供給下における吸光度計測にもとづいて，酸素吸脱着に適した金属ポルフィリン錯体の検討を行った．その上で，酸素吸脱着に伴う電気化学応答を基礎的に調べることで，デバイス応用に向けた基礎的な知見を得た．
