Template-Directed Molecular Nanostructures on the Ag/Pt(111) Dislocation Network

Abstract

We report on the high effectiveness of the Ag/Pt(111) dislocation network template for guiding the formation of well-ordered perylenetetracarboxylic diimide (PTCDI) molecular nanostructures due to its laterally strong inhomogeneous properties. Numerous PTCDI nanostructures show chiral arrangements driven by specific substrate−molecule and molecule−molecule interactions, with a higher strength coming from the substrate, which, per molecule, is quantified by simulations to be at least in the same order as a hydrogen bond.
