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.
