2，6-二[二丁氨基苯基乙烯]-1-丁基吡啶碘化物(Bu(2)NphiV)(2)BuPy+I-，1夹在金电极之间的单层整流被观察到。在0.5V到1.0V的正向偏压下，由于电子优先从碘离子流向吡啶环，电流得到增强，电流高达10万电子分子(-1)S(-1)，整流比高达90。
Rectification was observed across a monolayer of 2,6-di [dibutylamino-phenylvinyl]- 1-butylpyridinium iodide, (Bu(2)NphiV)(2)BuPy+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.
