Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Multicomponent network formation by using a shape‐persistent macrocycle (<bold>MC6</bold>) at the interface between an organic liquid and Au(111) surface is demonstrated. <bold>MC6</bold> serves as a versatile building block that can be coadsorbed with a variety of organic molecules based on different types of noncovalent interactions at the liquid–solid interface. Scanning tunneling microscopy (STM) reveals the formation of crystalline bicomponent networks upon codeposition of <bold>MC6</bold> with aromatic molecules, such as fullerene (C₆₀) and coronene. Tetracyanoquinodimethane, on the other hand, was found to induce disorder into the <bold>MC6</bold> networks by adsorbing on the rim of the macrocycle. Immobilization of <bold>MC6</bold> itself was studied in two different noncovalently assembled host networks. <bold>MC6</bold> assumed a rather passive role as a guest and simply occupied the host cavities in one network, whereas it induced a structural transition in the other. Finally, the central cavity of <bold>MC6</bold> was used to capture C₆₀ in a complex three‐component system. Precise immobilization of organic molecules at discrete locations within multicomponent networks, as demonstrated here, constitutes an important step towards bottom‐up fabrication of functional surface‐based nanostructures.</p> </abstract>
