Monolayers of Functionalized Oligothiophenes on Graphite—STM Investigation of the Influence of Intermolecular Interactions on the Epitaxy

Abstract

Intermolecular interactions caused by substituents, van der Waals interactions, hydrogen bonds, etc. need to be understood if the directed formation of supramolecular structures is to succeed. A study of the influence of intermolecular and substrate–molecule interactions on the epitaxy of monolayers of terminally mono- and disubstituted 3,3-dipentyl-α-quinquethiophenes such as that shown in the Figure is presented.
