The development of materials and devices at the nanoscale presents great challenges, from synthesis to assembly to characterization. Often, progress can only be made by complementing work with electronic-structure modeling, harnessing the efficiency, predi ...
New enantiomerically pure alleno-acetylenic macrocycles were prepd. by oxidative homocoupling of optically active 1,3-diethynylallenes. Enantiomer sepn. resulted from a combined strategy of synthesis and chiral HPLC techniques. Two other achiral stereoisom ...
Three substituted-pyridyl functionalized bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) derivatives 1-3 and their corresponding Ni(II) and Co(II) complexes have been synthesized and characterized. Their electrochemical properties in CH2Cl2 solution have ...
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 ...
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 ...
In this thesis, we present Scanning Tunneling Microscopy investigations of two-dimensional supramolecular architectures and metallic nanostructures on pre-structured surfaces. We studied different self-assembled supramolecular architectures formed by linea ...
The discrete regulation of supercoiling, catenation and knotting by DNA topoisomerases is well documented both in vivo and in vitro, but the interplay between them is still poorly understood. Here we studied DNA catenanes of bacterial plasmids arising as a ...
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 ...
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 ...
The contribution of the solvation energies to the assembly of polynuclear helicates reduces the free energy of intermetallic repulsion, DEMM, in condensed phase to such an extent that stable D3-symmetrical tetranuclear lanthanide-containing triplestranded ...
