Spontaneous Discrimination of Polycyclic Aromatic Hydrocarbon (PAH) Enantiomers on a Metal Surface

Spontaneous Discrimination of Polycyclic Aromatic Hydrocarbon (PAH) Enantiomers on a Metal Surface

Surface control: Vacuum deposition of a planarized PAH (C60H30) on a Pt(111) surface induces chirality caused by the different landing side of the molecule, as shown by in situ STM images. The surface determines the landing side of individual molecules, which present different structural geometries...

Zusammenfassung:Surface control: Vacuum deposition of a planarized PAH (C60H30) on a Pt(111) surface induces chirality caused by the different landing side of the molecule, as shown by in situ STM images. The surface determines the landing side of individual molecules, which present different structural geometries that are shifted by about 35° (see figure). Large‐scale calculations explain the atomistic mechanism of the process.
