Surface value : Scanning tunneling microscopy reveals that aryl–carbonyl assemblies form through CH⋅⋅⋅O interactions on a Pt(111) surface (see picture). The strong hydrogen bonding is activated by the chemisorption‐induced polarization of the arene and is tunable by substitution on the aromatic ring. These findings are relevant to stereoselective heterogeneous and homogeneous catalysis.
