Functionalised clathrochelate complexes as supramolecular building blocks

The work presented in this thesis entails the synthesis and characterisation of new iron(II) tris(dioxime) clathrochelate complexes functionalised with apical capping groups suitable for supramolecular applications, and their subsequent incorporation into ...

Reversible Local and Global Switching in Multicomponent Supramolecular Networks: Controlled Guest Release and Capture at the Solution/Solid Interface

Magalí Alejandra Lingenfelder, Fernando Pablo Cometto

Dynamically switchable supramolecular systems offer exciting possibilities in building smart surfaces, the structure and thus the function of which can be controlled by using external stimuli. Here we demonstrate an elegant approach where the guest binding ...

Local Conformational Switching of Supramolecular Networks at the Solid/Liquid Interface

Klaus Kern, Magalí Alejandra Lingenfelder, Fernando Pablo Cometto

We use the electric field in a scanning tunneling microscope to manipulate the transition between open and close packed 2D supramolecular networks of neutral molecules in nonpolar media. We found that while the magnitude of the applied field is not decisiv ...

Facile synthesis of oligoyne amphiphiles and their rotaxanes

Holger Frauenrath, Stephen Schrettl, Tobias Hoheisel, Ruth Szilluweit, Martin Fritzsche, Emmanuel Romaric Contal

Carbon-rich organic compounds containing a series of conjugated triple bonds (oligoynes) are relevant synthetic targets, but an improved access to oligoynes bearing functional groups would be desirable. Here, we report the straightforward synthesis of two ...

The importance of dynamics in integrative modeling of supramolecular assemblies

Matteo Dal Peraro, Luciano Andres Abriata, Giorgio Elikem Tamo

Revealing the atomistic architecture of supramolecular complexes is a fundamental step toward a deeper understanding of cellular functioning. To date, this formidable task is facilitated by an emerging array of integrative modeling approaches that combine ...

Light absorption in 1D and 2D nanostructured organic semiconductors

Damien Rolland

Organic photovoltaics will be one of the corner stones in solving the increasing world's energy demand issue. For this reason, a better understanding of the detailed mechanisms involved in energy conversion in the employed nanostructured materials is still ...

Reversible supramolecular modification of surfaces

Negar Moridi

Enzymes are biocatalysts widely used in a large number of industrial biotech processes as they offer clear advantages over their chemical counterparts. Indeed, enzymes often show high substrate selectivity along with elevated turnover rates. Enzymatic cata ...

Supramolecular assemblies of organotin(IV)-diphosphoryl adducts: insights from X-rays and DFT

Kurt Schenk

Mono-, di- and tri-phenyltin(IV) adducts containing a neutral diphosphoryl ligand, Ph2P(O)OC6H4OP(O) Ph-2, were synthesized and characterized. These 2 : 1 adducts of two trans-organotin(IV) moieties and the bridging ligand all crystallize around a centre o ...

A heterometallic macrocycle as a redox-controlled molecular hinge

Rosario Scopelliti, Kay Severin, Clément Schouwey, Marcus Papmeyer

The ability to modify the structure of nanoscopic assemblies in a controlled fashion is an important prerequisite for the creation of functional supramolecular systems. Here, we describe a heterometallic Pt2Cu2-macrocycle which behaves as a molecular hinge ...

Exploiting Dispersion-driven Aggregators as a Route to New One-dimensional Organic Nanowires

Riccardo Petraglia, Adrien Georges Nicolai, Hongguang Liu

The efficiency of charge carrier mobility in organic semiconductors is heavily dependent upon the long-range organization (i.e., morphology) and the local relative arrangement of the transporting molecules. Here, we exploit London dispersion forces as a de ...
