Conformational flexibility of a rotaxane thread probed by electronic spectroscopy in helium nanodroplets

Marcel Drabbels

Ultra-high-resolution spectroscopic studies have been performed to elucidate the conformational landscape of the succinamide-based thread 1 that is frequently employed in mechanically interlocked molecular assemblies. We show how dissolving single molecule ...

Self-assembly of boron-based supramolecular structures

Nicolas Christinat

This work describes the synthesis and characterization of boronic acid-based supramolecular structures. Macrocycles, dendritic structures, polymers, rotaxanes, and cages were assembled using four types of reversible reactions. The key point of the strategy ...

Efficient synthesis of cyclic glycolipids analogues

Sandrine Gerber, Gérald Coste

A straightforward approach to macrocyclic structures containing deoxysugar subunits was developed through the functionalization of a bishemiketal. The choice of the length and the nature of the linkers can provide macrocycles with diverse rigidities and po ...

Template-directed supramolecular self-assembly of coordination dumbbells at surfaces

Klaus Kern

Scanning tunneling microscopy reveals, at single-molecular resolution, how external parameters-substrate morphology and guest addition-re-direct the assembly of dumbbell-shaped coordination supramolecules towards different surfaceconfined supramolecular or ...

Toward mechanical switching of surface-adsorbed [2]catenane by in situ copper complexation

Klaus Kern, Stephan Rauschenbach, Dietmar Payer

Using scanning tunneling microscopy (STM), electrospray ionization mass spectrometry (ESI-MS), and X-ray photoelectron spectroscopy (XPS), we demonstrate that a free (2]catenane consisting of two interlocking 30-membered rings (cat-30) can be deposited on ...

Single-molecule-level characterization of supramolecular systems at surfaces

Dietmar Payer

This thesis deals with the self-organization of individual building blocks, specifically organic molecules and metal atoms, into supramolecular structures on metal surfaces under ultra high vacuum conditions (UHV). Self-organization of supramolecular syste ...

Block copolymer micelles as switchable templates for nanofabrication

Jürgen Brugger, Sivashankar Krishnamoorthy

Block copolymer inverse micelles from polystyrene-block-poly-2-vinylpyridine (PS-b-P2VP) deposited as monolayer films onto surfaces show responsive behavior and are reversibly switchable between two states of different topography and surface chemistry. The ...
