| Research Abstract |
A quaternary ammonium-type ionic liquid with terminal olefins was synthesized and its self-assembled monolayer was prepared. The obtained ionic liquid-modified electrode had spaces due to steric and electrostatic repulsions among the ionic liquid units on the electrode. Then, a diiron complex, which was able to activate O2 molecule, was introduced into the spaces on the electrode. Finally, terminal olefins were cross-linked by the olefin metathesis reaction with Grubbs reagent. The diiron complex was strongly immobilized in the ionic liquid layer. From the measurements by a rotating ring-disk electrode, the number of electrons during the O2 reduction was n = 3.8, indicating that the 4-electron reduction process was dominant.
