Self-assembled monolayer electrode of a diiron complex with a phenoxo-based dinucleating ligand: observation of molecular oxygen adsorption/desorption in …
The phenoxo-based dinucleating ligand, 2, 6-bis [bis (6-pivalamido-2-pyridylmethyl) amino- methyl]-4-aminophenol (1), and its Fe2 (II) complex,[Fe2 (II)(1)(PhCOO) 2](CF3SO3)(2), were prepared and 2 deposited on the Au surface (2/Au) is much more stable than in solution and exhibits redox behavior in aqueous media as well as reversible adsorption/desorption of oxygen at room temperature.
