Scanning tunneling microscopy of individual molecules: beyond imaging

Supramolecular Patterned Surfaces Driven by Cooperative Assembly of C60 and Porphyrins on Metal Substrates

“…[22] The individual molecules in the STM images are represented as groups of four lobes arranged in a slightly distorted square shape (Figure 1 a, left). According to earlier experiments conducted on tetra-arylated porphyrins, [18] each lobe in the STM image results from preferential tunneling transport through the 3,5-di(tert-butyl)phenyl substituents.…”

“…[15][16][17] However, the study of the C 60 -porphyrin interaction on solid surfaces is largely unexplored. [18] The formation of self-assembled molecular layers that are weakly physisorbed on surfaces provides the conceptional basis to engineer addressable fullerene-porphyrin architectures in which both chromophores are proximally assembled by noncovalent interactions. Herein we report on the bottom-up fabrication of patterned surfaces based on unprecedented two-dimensional (2D) supramolecular assemblies composed of porphyrins and C 60 .…”

Growth and characterization of fullerene nanocrystals on NaCl/Au(111)

“…In the past, the structure of supermolecular architectures arising from co-sublimation of C 60 molecules and different types of flat hydrocarbons has been investigated and interesting supermolecular patterns have been observed 18,[61][62][63] . These experiments motivated us to study, with special emphasis on the molecular orientation, the supramolecular structures within fullerene nanocrystals which may result from a mutual embedding of C 60 and C 70 molecules supported on a dielectric NaCl surface.…”

Viral capsomere structure, surface processes and growth kinetics in the crystallization of macromolecular crystals visualized by in situ atomic force microscopy

“…They have also served as mechanisms for molecular repositioning [9,10] and selective cleavage of molecular bonds [11]. They have been used to investigate reconstruction of semiconductor surfaces upon cleavage, epitaxial growth, annealing, deposition of surfactant layers, even controlled manipulation of individual atoms [12].…”
