Supporting information Van der Waals interactions in the self-assembly of 5-amino [6]helicene on Cu(100) and Au(111)
The experiments were carried out in an ultrahigh vacuum system equipped with a variable-temperature STM from Omicron Nanotechnology. The base pressure of the chamber was in the low 10-10 mBar range. The Cu(100) and Au(111) surfaces were prepared by cycles of sputtering with Ar at 1.5 keV and annealing at 770 K. The M-AH molecules were evaporated from a resistivity heated BN crucible at a rate o...
متن کاملHighly Sensitive Detection of H2S Molecules Using a TiO2-Supported Au Overlayer Based Nanosensors: A Van Der Waals Corrected DFT Study
The adsorption of the H2S molecule on the undoped and N-doped TiO2 anatase supported Au nanoparticles were studied using density functional theory calculations. The adsorption of H2S on both Au and TiO2 sides of the nanoparticle was examined. On the TiO2 side, the fivefold coordinated titanium site was found to be the most favorable binding site, giving rise to the strong interaction of H2S wit...
متن کاملInterfacial charge rearrangement and intermolecular interactions: Density-functional theory study of free-base porphine adsorbed on Ag(111) and Cu(111).
We employ dispersion-corrected density-functional theory to study the adsorption of tetrapyrrole 2H-porphine (2H-P) at Cu(111) and Ag(111). Various contributions to adsorbate-substrate and adsorbate-adsorbate interactions are systematically extracted to analyze the self-assembly behavior of this basic building block to porphyrin-based metal-organic nanostructures. This analysis reveals a surpri...

Reaction mechanism among indoline-2,3-dione, pyrrolidine-2-carboxylic acid and (Z)-2-(1-(2-hydroxynaphthalen-1-yl)ethylidene)hydroxycarboxamide to form 1’-((((aminooxy)carbonyl)amino)methyl)-2’-(1-hydroxynaphthalen-2-yl)-2’-methyl-1’,2’,5’,6’,7’,7a’-hexahydrospiro[indoline-3,3’-pyrrolo[1,2-a]imidazole-2-one was investigated using density functional theory (DFT) at B3LYP basis theory. The three-...
متن کاملThe role of van der Waals forces in water adsorption on metals.
The interaction of water molecules with metal surfaces is typically weak and as a result van der Waals (vdW) forces can be expected to be of importance. Here we account for the systematic poor treatment of vdW forces in most popular density functional theory exchange-correlation functionals by applying accurate non-local vdW density functionals. We have computed the adsorption of a variety of e...
