Halogen bond-directed self-assembly in bicomponent blends at the solid/liquid interface: effect of the alkyl chain substitution position

Abstract

The fabrication of well-organised molecular assemblies on surfaces is fundamental for the creation of functional molecular systems applicable to nanoelectronics and molecular devices. In this study, we investigated the effect...

Analysis of intermolecular interactions ofn-perfluoroalkanes with circumcoronene using dispersion-corrected DFT calculations: comparison with those ofn-alkanes

“…Molecular adsorption on surfaces is also crucial in the formation of nanostructures via self-assembly on surfaces, and exhibits considerable potential for application in the fields of nanoelectronics, molecular devices, lithography masks, etc. 3 Various intermolecular interactions, such as hydrogen bonding, 4 metal coordination, 5 halogen bonding 6 and dispersion forces 7 are exploited in self-assembly. On the highly ordered pyrolytic graphite (HOPG) surface, the alkyl chains are critical in enhancing the stabilities of the adsorbed molecules.…”

A Paradigm Shift from 2D to 3D: Surface Supramolecular Assemblies and Their Electronic Properties Explored by Scanning Tunneling Microscopy and Spectroscopy

“…Another kind of candidate for constructing 3D assembled architecture is dehydro-benzo [12]annulenes (DBAs). Due to the planar triangular π-electron-conjugated framework and suitable core size to favor directional alkyl chain interdigitation, DBAs have been widely used to form 2D porous networks.…”

“…Using organic molecules as the nanoscale building blocks, the concept of molecular selfassembly has become an integrated strategy for building molecular-based devices. [4][5][6] In general, the self-assembly process mainly relies on noncovalent interactions such as hydrogen bonding, [7][8][9] halogen bonding, [10][11][12][13] van der Waals interaction, [14][15][16] π-π interaction, [17][18][19] electrostatic interaction, [20][21][22] Exploring supramolecular architectures at surfaces plays an increasingly important role in contemporary science, especially for molecular electronics. A paradigm of research interest in this context is shifting from 2D to 3D that is expanding from monolayer, bilayers, to multilayers.…”

Tuning the odd–even effect on two-dimensional assemblies of curcumin derivatives by alkyl chain substitution: a scanning tunnelling microscopy study

“…Fine-tuning of supramolecular structures on surfaces is essential for the fabrication of functional nanomaterials and molecular machines. 1 By introducing noncovalent interactions such as dispersion forces, 2 metal coordination, 3 hydrogen bonding, 4 and halogen bonding, 5 various types of fascinating supramolecular structures have been constructed. Scanning tunnelling microscopy (STM) has been used for the direct visualization of two-dimensional (2D) molecular arrangements on surfaces.…”
