Erratum: Extended One-Dimensional Supramolecular Assembly on a Stepped Surface [Phys. Rev. Lett.100, 046103 (2008)]

Mesoscopic Arrays from Supramolecular Self‐Assembly

“…In the latter case, high‐order superstructures provide a denser packing but are energetically less favored and can be obtained only at increasing surface coverage: the superstructure size is an extensive property of the system. The formation of one‐dimensional templates or nanogratings with large (mesoscopic) interline distances has also been reported, but again the periodicity was directly related to the molecular coverage 21–23. Herein we present an exceptionally large two‐dimensional organic template (22 nm superperiod) that is a thermodynamic equilibrium phase.…”

Self-assembled one-dimensional soft nanostructures

“…In a recent study, formation of 1-D nanostructures on defected structures has been demonstrated. 81 2,6-naphtalene-dicarboxylic acid molecules were adsorbed on stepped (110) silver surfaces, producing mesoscale 1-D chains. The average length of the chains had a lower limit of 0.14 mm with the longest chain being nearly five times longer; the average number of steps crossed by a single chain was 2.3.…”

Molecular self-organization: Predicting the pattern diversity and lowest energy state of competing ordering motifs

“…Based on an energy analysis of the Monte Carlo and molecular mechanics modeling the thermodynamically most stable pattern is predicted coinciding with the pattern, which dominates in the STM images after several hours or upon moderate heating. Organic molecules mainly self-organize via hydrogen bonds, [1,2] metal-coordination [3] and van der Waals interactions [4]. Voices have been raised, [5,6] that more innovative modeling approaches [7,8] are necessary in order to analyze and predict molecular patterns for fostering applications in surface functionalization [9], sensors [10], catalysis [11], and in molecular electronic devices [12].…”

“…This covers the dominant intermolecular interactions stemming from the alkoxy chains, statistically contributing an interaction strength of 14 kJ/mol per four CH 2 -units for more than half but not fully interdigitated alkoxy chains on graphite (previous studies yield 18 kJ/mol for fully and 8.5 kJ/mol for half-interdigitated alkoxy chains on graphite surfaces [25]). We have calculated the van der Waals part of the total energy I) of a substrate supported monolayer in MM energy minimized geometry, i sup , II) of a gas phase net [2], i gn , and III) of one isolated molecule, i iso . With that we can carefully separate the intermolecular interaction (chainneighboring-chain) part I c−n−c /molecule= (i gn /n) − i iso from the substrate interaction (molecule -substrate) part I m−s /molecule= (i gn − i sup )/n of the van der Waals energy per molecule, with n, the number of molecules per unit cell (see Table I a).…”
