Abstract

original image

Repulsive interactions: A staging of supramolecular aggregation from (0D) clusters to (1D) chains and (2D) assemblies as a function of molecular coverage of dipolar porphyrins adsorbed on the Ag(111) surface is described. It displays a complex interplay of both attractive and repulsive molecule–molecule interactions, the emergence of chirality, and the registry of the substrate (see figure).
