Upon deposition of an achiral solution of diarylethene 1 on the achiral surface of graphite, a highly ordered monolayer with large homochiral domains is formed by self-assembly. Scanning tunneling microscopy and molecular dynamics show that the building blocks forming this monolayer are chiral dimers. We suggest that the mechanism of formation of these chiral dimers is first, surface-induced atropoisomerism, which provides diarylethene 1 with a fixed helicity, and second, shape recognition between atropoisomers having similar helicities.
