Observation of current rectification by a new asymmetric iron() surfactant in a eutectic GaIn|LB monolayer|Au sandwich
In this paper we expand on the search for molecular rectifiers of electrical current and report on a hexacoordinate metallosurfactant [Fe III (L N 3 O )(OMe) 2 ], where (L N 3 O ) − is the deprotonated form of the new asymmetric ligand 2-(( E )-((4,5-bis(2-methoxyethoxy)-2-((( E )-pyridin-2-ylmethyl...

This surfactant, as a Langmuir-Blodgett monolayer on Au, has electrical rectification ratios from 25 to 300 at 1 Volt (the coordinating Ns are the electron donors, Fe(

) is the electron acceptor). The red arrow shows the direction of preferred electron current. |
