Bicomponent Supramolecular Packing in Flexible Phthalocyanine Networks

Abstract

Zwischen den Zeilen lesen: Bei der Adsorption von Octachlorzinkphthalocyanin‐Molekülen auf Ag(111) wird die Bildung dreier schwach gebundener Netzwerke beobachtet. Der Einbau von Corannulenmolekülen in diese Phasen – zur Bildung stabiler Reihen oder schachbrettartiger Muster – lässt sich rastertunnelmikroskopisch nachweisen (siehe Bild). Nach dem Entfernen der Corannulenmoleküle bei 4.6 K verbleiben künstliche Muster auf der Oberfläche.

Bicomponent Supramolecular Architectures at the Vacuum–Solid Interface

“…Moreover, molecular ordering on a surface may take hours to reach large domains, due to a slow release of constraints originating from the incommensurability between the molecular scaffold and the registry of the surface. This process occurs, for instance, with ZnPcC l8 molecules on Ag(111), 344,342 for which a maturation process at RT was observed with a structural evolution through three extended phases over almost fifty hours. Finally, the structure of the surface itself can be an obstacle due to complicated reconstructions (semiconductor surfaces), a long-range structure (the well-known 22  3 structure of the Au surface) or the presence of defects.…”

Robust and Open Tailored Supramolecular Networks Controlled by the Template Effect of a Silicon Surface

“…), which can be used as building blocks for the growth of highly ordered supramolecular structures (i.e. [4][5][6][7][8][9][10][11][12] Supramolecular engineering is based on the subtle balance between molecule-molecule interactions and molecule-substrate interactions. [2] Once the mechanisms that control the self-ordering phenomena are fully understood, the selfassembly and growth processes can create a wide range of nanostructured surfaces from metallic, semiconducting, and molecular materials.…”

“…[27] Many works have discussed the trapping of fullerenes in molecular nanoporous networks on noble-metal surfaces [10,17,18,[28][29][30][31][32] or on semiconductor surfaces. The substrate template effect stems from the matching of the geometrical parameters of the surface and the TBB molecules (size and symmetry).…”

Two-dimensional molecular sieves: structure design by computer simulations

“…In particular we focus on those molecules which are not prochiral, that is they do not deconvolute into mirror-image structures upon adsorption. The simplest example of a molecule of this kind is the C 4 -symmetric molecule (1111) whose structure resembles that of small phthalocyanines or porphyrins (Calmettes et al 2008). Figure 2a shows a snapshot of the simulated overlayer comprising 1000 molecules of (1111) (brown).…”

“…Our study was inspired by the experimental results which have been recently reported for phthalocyanines and their alkyl-substituted analogs self-assembled on graphite (Miyake et al 2008) and metallic surfaces (Calmettes et al 2008). …”
