Transition from Homochiral Clusters to Racemate Monolayers during 2D Crystallization of Trioxa[11]helicene on Ag(100)

The front cover artwork is provided by Prof. Ernst from Empa. The image shows determination of the sense of helicity of trioxa[11]helicene enantiomers with an atomic force microscope, which allows discrimination between homo‐ and heterochiral 2D self‐assembly.
