“…We include the case of two NCs with different radii and explore the long hydrocarbon chains investigated in real experiments. Previous studies focused primarily on the potential of mean force, starting with those performed by Schapotschnikow et al [28][29][30] Subsequent investigations have studied the role of solvent, 31,32 more detailed density functional theories, 33 as well as different approaches to the PMF 34 and three body effects. 35 The relation of this work to our results is discussed further below.…”

“…3 The anisotropic forces responsible for this fcc-bcc transition observed at larger R LC originate in the self-organization of ligands, which form bundles, and tend to arrange NPs in linear chains. 4,5 Monolayers of colloidal NPs have also been formed on solid substrates 6,7 and solvent interfaces. 8,9 Their electrical [10][11][12] and optical properties 13,14 of depend on the NP type, size, ligands, 15 and substrate used.…”

“…Ein wichtiger Beitrag war Formulierung eines speziellen Kraftfeldes für Gold-Gold-und Gold-Molekül-Wechselwirkungen, wodurch sowohl Gold-Nanokristalle als auch deren Assoziation an Alkylthiolmoleküle zugänglich wurden. [109] Darauf aufbauend ließen sich MC-Simulationen durchführen, um die Struktur einer selbstorganisierten Monoschicht (SAM) aus Alkylthiolmolekülen auf einem Gold-Ikosaeder zu untersuchen. [110] Im Rahmen eines großkanonischen Ansatzes umfasste dies auch Versuche, Alkylthiolmoleküle einzufügen bzw.…”

“…[112] Es ist offensichtlich, dass selbst solch kleine Agglomerate von Nanokristallen einen erheblichen Rechenaufwand bedeuten und wir zugleich immer noch weit von der Aggregation eines Kompositmaterials entfernt sind. Mithilfe von Coarse-Graining-Ansätzen zur Vergröberung der Modelle (was zum Teil bereits erfolgte) [109] und durch die Anwendung von geeigneten Algorithmen zur Bewältigung von Keimbildungsprozessen (wie in Abschnitt 2 beschrieben) erscheint die molekulare Simulation der Aggregation von Goldnanokristall-Alkylthiol-SAM-Kompositen jedoch in Reichweite gerückt zu sein.…”
