Abstract

Adsorption of sub-monolayer amounts of 1-nitronaphthalene (NN) onto Au(111) leads to the aggregation of NN decamers, which exhibit two-dimensional chirality and represent a racemic mixture. In analogy to Pasteur's experiment of 1848 a scanning tunneling microscope can be used to discriminate and separate the enantiomers on a molecular scale.

Keywords: Chirality; Enantiomeric resolution; Nanostructures; Scanning tunneling microscopy.
