Nanostructured Organic Material: From Molecular Chains to Organic Nanodots

Abstract

Deposition of 3,4,9,10‐perylene‐tetracarboxylic‐dianhydride on iron island arrays on Au(111) results in the formation of new nanostructures. By controlling the amount of iron deposited on the gold surface, two kinds of aggregates are obtained: molecular chains and organic nanodots (see figure). These nanostructures possess a different density of states from the two‐dimensional self‐assembled molecular layer.

Two-Dimensional Nanotemplates as Surface Cues for the Controlled Assembly of Organic Molecules

“…Another strategy for the growth of metal-organic nanostructures made use of a Au(111) surface patterned with Fe islands arrays [98]. The Fe arrays were formed spontaneously upon Fe deposition via strain relief nucleation at the elbows of the herringbone reconstructed Au surface.…”

Hierarchical Organisation on a Two‐Dimensional Supramolecular Network

“…[3] This is of particular relevance to spontaneous organisation on surfaces, [2, a rapidly developing research field with great promise for applications such as biosensors and molecular electronics. Example of hierarchical organisation of molecular clusters was recently demonstrated by Blüm et al [4] and Spillmann et al [5] In addition, several examples of systems which display multiple levels of organisation have been realised through an interplay of molecular self-assembly and a second physical ordering mechanism arising from, for example, surface reconstruction [8,13,17,26,27] or dewetting. [28] Herein we show that hierarchies of organisation may be introduced intrinsically by a self-assembled two-dimensional network.…”

Control over Patterning of Organic Semiconductors: Step‐Edge‐Induced Area‐Selective Growth

“…The strategy provides control over structure, size and morphology of various materials at predefined areas, either by adsorption/desorption [8,9] or diffusion/binding processes. [10][11][12] The templates for inducing the growth of materials are chemically patterned, and the binding-energy differences of the deposited material at different locations on the template are responsible for the ASG. Recently, we introduced an ASG concept to pattern organic molecules by vacuum deposition.…”
