Supramolecular building blocks: The adsorption of the oligopyridine isomers 2,4′-BTP and 3,3′-BTP on graphite (see picture) is studied with force field and dispersion-corrected density functional theory (DFT-D) methods. Whereas the used force fields yield different adsorption geometries and strongly varying adsorption energies, the adsorption energy obtained with DFT-D is in rather good agreement with experiment.
