On‐Surface Assembly of Au‐Dicyanoanthracene Coordination Structures on Au(111) [PDF]

ChemPhysChem, 2019
AbstractOn‐surface metal‐organic coordination provides a promising way for synthesizing different two‐dimensional lattice structures that have been predicted to possess exotic electronic properties. Using scanning tunneling microscopy (STM) and spectroscopy (STS), we studied the supramolecular self‐assembly of 9,10‐dicyanoanthracene (DCA) molecules on ...

Thioetherification of Br-Mercaptobiphenyl Molecules on Au(111)

Nano Letters, 2023
Thioether polymers are fundamental for a variety of applications. Their synthesis is, however, more challenging than that of other metal-catalyzed reactions due to the reported detachment of the S atom during thermal activation. In this study, it has been demonstrated unambiguously that thermal annealing results in the thioetherification of the 4-bromo-

Controlling the Spin States of FeTBrPP on Au(111)

ACS Nano, 2022
Spin-flip excitations of iron porphyrin molecules on Au(111) are investigated with a low-temperature scanning tunneling microscope. The molecules adopt two distinct adsorption configurations on the surface that exhibit different magnetic anisotropy energies.

Гідрофілізація поверхні Au(111), функціоналізованої алкантіолами

Хімія, фізика та технологія поверхні, 2016
Досліджено гідрофільні властивості поверхні Au(111), модифікованої алкантіолами різної довжини та з різними функціональними групами. Виявлено, що для впорядкованих моношарів алкантіолів змочування поверхні залежить від типу термінальних груп молекул ...

Thermally Driven Structural Order of Oligo(Ethylene Glycol)-Terminated Alkanethiol Monolayers on Au(111) Prepared by Vapor Deposition

Molecules, 2022
To probe the effects of deposition temperature on the formation and structural order of self-assembled monolayers (SAMs) on Au(111) prepared by vapor deposition of 2-(2-methoxyethoxy)ethanethiol (CH3O(CH2)2O(CH2)2SH, EG2) for 24 h, we examined the ...

Melamine Structures on the Au(111) Surface

The Journal of Physical Chemistry C, 2008
We report on a joint experimental and theoretical study of the ordered structures of melamine molecules formed on the Au(111)-(22 x root 3) surface. Scanning tunneling microscopy (STM) images taken under UHV conditions reveal two distinct monolayers one of which has never been reported before on gold.

Theoretical Study of CO Adsorption on Perfect and Defective Gold Surfaces

Adsorption Science & Technology, 2013
The activities of Au(111), Au(100) and Au(110) surfaces, as well as the activity of an Au adatom on Au(111), Au(100) and Au(110) surfaces have been characterized by density functional theory using CO as a probe. The results clearly show that the activity

Inelastic scattering of formaldehyde on Au(111) surface

The Journal of Chemical Physics, 2023
Inelastic scattering between gas molecules and surfaces is a fundamental process that has been investigated extensively. In recent gas-surface scattering experiments [Phys. Chem. Chem. Phys. 19, 19904 (2017)] on formaldehyde scattering off the gold surface, the scattered formaldehyde molecules had a high propensity to excite twirling motion about the C–

Electronic structure and adsorption stability of ferrocene on Au (111) and Ag (111) surfaces

JPhys Materials
The adsorption behaviours and electronic structures of ferrocene (Fc) on Au(111) and Ag(111) surfaces were investigated using density functional theory. Two Fc conformers, eclipsed (E-Fc) and staggered (S-Fc), were studied in vertical (⊥) and parallel (||
