Current affairs : The electron‐transport properties of a metal–molecule–metal junction based on two contacting redox‐active self‐assembled monolayers of [Ru(NH 3 ) 5 (NC 5 H 4 ‐4‐CH 2 NHCO(CH 2 ) 10 SH](PF 6 ) 2 (see picture) is described. The junction becomes conductive when the electrode potentials are adjusted to the formal potential of the redox centers and shows diode‐ and transistor‐like characteristics analogous to those of solid‐state devices.
