Well-organised two-dimensional self-assembly controlled byin situformation of a Cu(ii)-coordinated rufigallol derivative: a scanning tunnelling microscopy study

Abstract

The two-dimensional self-assembly of rufigallol derivatives and their metal coordination were studied by scanning tunnelling microscopy. Ex-situ Cu(II)-coordinated rufigallol derivatives exhibited columnar structures with some defects, whereas regular and linear...

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.…”

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.…”

Metal Ion and Guest-Mediated Spontaneous Resolution and Solvent-Induced Chiral Symmetry Breaking in Guanine-Based Metallosupramolecular Networks

“…Surface-confined MOCNs are typically characterized using scanning probe methods, especially scanning tunneling microscopy (STM). , STM images provide unprecedented resolution while revealing several structural aspects including the nature and the extent of defects that often go unnoticed in ensemble measurements. While STM can be carried out both under ultrahigh vacuum (UHV) conditions and at the solution–solid interface, the former dominates the literature. , There exist only a few reported examples of one-dimensional (1D) and 2D MOCNs constructed and characterized at the solution–solid interface. − Despite the challenges associated with STM imaging in the presence of metal-ion solutions, STM characterization of MOCNs at the solution–solid interface at room temperature is valuable as it provides insight into the dynamical aspects of MOCN formation. STM has also been employed for the characterization of discrete metallosupramolecules. − Thin films of MOCNs , have been investigated using atomic force microscopy (AFM), and single-layered MOCNs have been imaged at molecular resolution using non-contact AFM …”
