Electrons leave the flatland: out-of-plane charge dynamics in layered materials

The goal of this thesis is to explore the "neglected" third dimension of layered materials, by studying the interlayer charge dynamics through dc conductivity, optical spectroscopy and ab-initio calculations. This project was designed to respond to the gro ...

Composition and method for the preparation of sheets, films, fibers, and molded parts

Holger Frauenrath, Daniel Görl, Oguzhan Oguz

The invention describes a composition containing a) a functionalized polymer (10) that comprises at least one polyester segment (13) and at least one, in particular at least two, polymer aggregating segment (11, 12) capable of forming non-covalent bonds ba ...

Engineering polymers with improved charge transport properties from bithiophene-containing polyamides

John Christopher Plummer, Rosario Scopelliti, Holger Frauenrath, Farzaneh Fadaei Tirani, Bilal Özen, Nicolas Candau

Polymer semiconductors show unique combinations of mechanical and optoelectronic properties that strongly depend on their microstructure and morphology. Here, we have used a model pi-conjugated bithiophene repeat unit to incorporate optoelectronic function ...

Assembly of High-Spin [Fe-3] Clusters by Ligand-Based Multielectron Reduction

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Davide Toniolo

The hexanuclear [Na12Fe6(tris-cyclo-salophen)(2)(THF)(14)], 1-THF, and the trinuclear [Na6Fe3(tris-cyclo-salophen)(py)(9)], 1-py, Fe(II) clusters can be easily assembled in one step from the ligand-based reduction of the [FeII(salophen)(THF)] complex. Thes ...

Revealing Single-Bond Anomeric Selectivity in Carbohydrate-Protein Interactions

Oleg Boyarkine, Aleksandr Pereverzev, Viktoriia Aladinskaia, Ruslan Yamaletdinov

The noncovalent binding of proteins to glycans is amazingly selective to the isoforms of carbohydrates, including alpha/beta anomers that coexist in solution. We isolate in the gas phase and study at the atomic level the simplest model system: noncovalent ...

Controlling Single Molecule Conductance by a Locally Induced Chemical Reaction on Individual Thiophene Units

Klaus Kern, Uta Schlickum, Peter Wahl, Hagen Klauk, Ivan Pentegov, Verena Katharina Schendel

Among the prerequisites for the progress of single-molecule-based electronic devices are a better understanding of the electronic properties at the individual molecular level and the development of methods to tune the charge transport through molecular jun ...

Spectroscopic Evidence for Peptide-Bond-Selective Ultraviolet Photodissociation

Oleg Boyarkine, Vladimir Kopysov, Aleksandr Pereverzev

We study the photodissociation induced by ultraviolet excitation of amide bonds in gas-phase protonated peptides. Jointly, mass spectrometry and cold ion spectroscopy provide evidence for a selective non-statistical dissociation of specific peptide bonds i ...

Hydrogen-Bonded Small Molecules and Polymers in Organic Electronics

Bilal Özen

Organic semiconductors are important components for applications in different fields of technology, as their advantages include the possibility of low-temperature processing as well as low-cost, large-area manufacturing based on solution-based processes, c ...

Small Molecule Activation by Multimetallic Uranium Complexes

Marta Falcone

The development of new processes for the selective and sustainable transformation of abundant small molecules constitutes one of the major research areas in inorganic and organometallic chemistry. These molecules as CO2, CO, N2 and H2 are abundant reservoi ...

Numerical investigation of the mixed-mode failure of snow

Johan Alexandre Philippe Gaume, Dominika Mulak

The failure of a weak snow layer underlying a cohesive slab is the primary step in the release process of a dry snow slab avalanche. The complex and heterogeneous microstructure of snow limits our understanding of failure initiation inside the weak layer, ...

Pivotal Role of the Basic Character of Organic and Salt Catalysts in C-N Bond Forming Reactions of Amines with CO2

Paul Joseph Dyson, Martin Hulla

Organocatalysts promote a range of C-N bond forming reactions of amines with CO2. Herein, we review these reactions and attempt to identify the unifying features of the catalysts that allows them to promote a multitude of seemingly unrelated reactions. Ana ...
