Building Supramolecular Nanostructures at Surfaces by Hydrogen Bonding

Abstract

The fine balancing of the lateral intermolecular interactions and the bonding to the substrate enables the self-assembly of supramolecular nanostructures at surfaces to be achieved. The scanning tunneling microscopy image shows the formation of a twin chain of 4-[trans-2-(pyrid-4-yl)vinyl]benzoic acid deposited on an Ag(111) surface in ultra-high vacuum.
