Supramolecular self-assembly of brominated molecules on a silicon surface.
نویسندگان
چکیده
Hydrogen and halogen bonds have been associated for the growth of 2D compact supramolecular networks on a silicon surface. These interactions have been elucidated in a complete monolayer of a 4,4''-dibromo-p-terphenyl (DBT) molecule on a Si(111)-B surface by combining scanning tunneling microscopy (STM) and density functional theory (DFT) calculations.

Supramolecular assemblies of 1,4-benzene diboronic acid on KCl(001)
The self-assembly of benzene diboronic acid molecules on KCl(001) is investigated at room temperature by means of non-contact Atomic Force Microscopy. When depositing the molecules on the freshly cleaved surface, the molecules self-assemble into an extended twodimensional supramolecular phase driven by H-bonds. Theoretical calculations based on Density Functional Theory show that the cohesion e...
متن کاملPredicting supramolecular self-assembly on reconstructed metal surfaces.
The prediction of supramolecular self-assembly onto solid surfaces is still challenging in many situations of interest for nanoscience. In particular, no previous simulation approach has been capable to simulate large self-assembly patterns of organic molecules over reconstructed surfaces (which have periodicities over large distances) due to the large number of surface atoms and adsorbing mole...

متن کاملSelf-Assembly under Confinement: Nanocorrals for Understanding Fundamentals of 2D Crystallization
Nanocorrals with different size, shape, and orientation are created on covalently modified highly oriented pyrolytic graphite surfaces using scanning probe nanolithography, i.e., nanoshaving. Alkylated diacetylene molecules undergo laterally confined supramolecular self-assembly within these corrals. When nanoshaving is performed in situ, at the liquid-solid interface, the orientation of the su...
