Nature of the Interaction of N,N′‑Diphenyl-1,4-benzoquinonediimine with Iron Oxide Surfaces and Its Mobility on the Same Surfaces

Short chain aniline oligomers are of interest for applications in organic electronics and as corrosion inhibitors for steel, requiring an improved understanding of their interactions with metal oxide films. Here we investigate the interactions of N,N′-diphenyl-1,4-benzoquinonediimine (B2Q1, oxidized form of an aniline dimer) with iron­(III) oxides. B2Q1 transforms into its semiquinone form when interacting with α-Fe2O3. The resulting charge …
