Molecular polygons with three to six sides and binary mixtures thereof form long-range ordered patterns at the TCB/HOPG interface. This includes also the 2D crystallization of pentagons. The results provide an insight into how the symmetry of molecules is translated into periodic structures.

A modular synthetic approach paves the way to nanoscale platform molecules for supramolecular graphite surface patterns at the solid–liquid interface. While a perylenedye bound at the end of the pillar remains fixed above the molecule center and points into solution, a fullerene ester bound at the same position performs a tumbling motion that translates as a “haze” in the otherwise submolecularly
