Engaging 1-Alkynyl Triazenes in Transition Metal-Catalyzed and Fluorinative Transformations

Jin Fay Tan

Triazenes have garnered great attention for their anti-cancer properties and versatility in organic chemistry. Recently, a novel synthesis of 1-alkynyl triazenes was reported. This thesis describes the compatibility, reactivity and applications of 1-alkyny ...

Electrosorption at metal surfaces from first principles

Nicola Marzari

Electrosorption of solvated species at metal electrodes is a most fundamental class of processes in interfacial electrochemistry. Here, we use its sensitive dependence on the electric double layer to assess the performance of ab initio thermodynamics appro ...

Aqueous metal-organic solutions for YSZ thin film inkjet deposition

Andreas Stephan Lesch

Inkjet printing of 8% Y2O3-stabilized ZrO2 (YSZ) thin films is achieved by designing a novel water-based reactive ink for Drop-on-Demand (DoD) inkjet printing. The ink formulation is based on a novel chemical strategy that consists of a combination of meta ...

Synthesis of Azoimidazolium Dyes with Nitrous Oxide

Rosario Scopelliti, Kay Severin, Euro Solari, Alexander Tskhovrebov

A new method for the synthesis of industrially important azoimidazolium dyes is presented. The procedure is based on a reagent which is rarely used in the context of synthetic organic chemistry: nitrous oxide (“laughing gas”). N2O is first coupled to N-het ...

Synthesis of Triazenes with Nitrous Oxide

Paul Joseph Dyson, Rosario Scopelliti, Kay Severin, Tina Riedel, Gregor Kiefer

Triazenes are valuable compounds in organic chemistry and numerous applications have been reported. Furthermore, triazenes have been investigated extensively as potential antitumor drugs. Here, we describe a new method for the synthesis of triazenes. The p ...

Studying sulfur functional groups in Norway spruce year rings using S L-edge total electron yield spectroscopy

Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis

Profiles of the major sulfur functional groups in mature Norway spruce wood tissue have been established for the first time. The big challenge was the development of a method suitable for sulfur speciation in samples with very low sulfur content (

Chiral kagome lattice from simple ditopic molecular bricks

Klaus Kern, Harald Brune, Uta Schlickum, Régis Decker

Self-assembly techniques allow for the fabrication of highly organized architectures with atomic-level precision. Here, we report on molecular-level scanning tunneling microscopy observations demonstrating the supramolecular engineering of complex, regular ...

Photoelectron Spectroscopy of Doped Helium Droplets

Marcel Drabbels, Evgeniy Loginov

The photoionization dynamics of aniline doped helium droplets has been investigated by photoelectron spectroscopy. The photoelectron spectra resemble closely that of gas phase aniline, except for a dropletsize- dependent shift. This shift is caused by lowe ...
