Popis:	Rectification was observed across a monolayer of 2,6-di[dibutylamino-phenylvinyl]-1-butylpyridinium iodide, (Bu2NφV)2BuPy+I-, 1 sandwiched between gold electrodes. The current is enhanced at a forward bias above 0.5 to 1.0 V, as electrons flow preferentially from the iodide ions to the pyridinium ring, and is as high as 100 000 electrons molecule-1 s-1, with a rectification ratio of up to 90.
