Conformation-Dependent Monolayer and Bilayer Structures of an Alkylated TTF Derivative Revealed using STM and Molecular Modeling

Abstract

In this study, the multilayer self-assembled molecular network formation of an alkylated tetrathiafulvalene compound is studied at the liquid–solid interface between 1-phenyloctane and graphite. A combined theoretical/experimental approach associating force-field and quantum-chemical calculations with scanning tunneling microscopy is used to determine the two-dimensional self-assembly beyond the monolayer but also to further the understanding of the molecular adsorption conformation and its impact on the molecular packing within the assemblies at the monolayer and bilayer level.
