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.
