An atomistic view of the the enantiomeric recognition of PAHs on single crystal metal surfaces

Recently published in Chemistry, a European Journal. Vacuum deposition of a planarized PAH, as C60H30 , on a single-crystal surface, as Pt(111), leads to surface induced chirality caused by the different landing side of the molecule, as depicted by in-situ STM images.

We show that the surface discriminate the landing side of an individual molecule. Molecules adsorbed “right” or “left”-hand present different structural geometries, shifted by about 35º between them. Large-scale DFT calculations explain the atomistic mechanism behind the enantiomeric recognition process.
