Research Abstract

An organic monolayer with diarylethene and viologen moieties as a photochromic and an electroactive group, respectively, was constructed on a Si(111) surface by sequential surface reactions. Photoswitching of electron transfer from the Si electrode to viologen moiety was demonstrated. Single molecular momentum measurement during the photochromic reaction of diarylethene is on-going.
