Optical investigations on PTCDA on KCl(100): Superradiant aggregates and single molecules
(2019-08-23)
In the present work, condensed and diluted phases of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) were investigated on thin KCl(100) films on the Ag(100) surface. The samples were structurally characterized by spot ...
Synthetic evolution of azobenzene and arylazopyrazole photoswitches and translation into photoresponsive DNA nanosystems
(2019-10-23)
Light as an external stimulus provides a powerful and versatile tool to control chemical reactions and biological systems. Light is easily available and permits a high spatial and temporal control while minimizing systemic ......
Strukturwandel von Chalkogen-Polykationen unter Druck
(2019-08-29)
Im Rahmen dieser Arbeit wurden die strukturellen Umwandlungen von Tellur- und Selen-Polykationen führenden Festkörpern unter dem Einfluss von hohem Druck untersucht. Einkristalle der zu untersuchenden Substanzen in geeigneter ......
Structural change of chalcogen polycations under pressure
This study is about high pressure phase transitions of mostly tellurium polycationic structures. Single crystals of roughly 0,1 mm size were ......

Evolution of the Activity Cliff Concept and Practical Implications for Compound Design
(2021-07-22)
Entering the “big data” era, a number of different research areas have witnessed an enormous increase in data at an exponential rate. For drug discovery, various publicly available protein structure and compound bioactivity ...
Komplexe Halogenidorhodate und Rhodiumchalkogenidhalogenide
(2019-07-04)
In der vorliegenden Arbeit wurden umfangreiche Untersuchungen zur Synthese und Charakterisierung neuer Halogenidorhodate (von Chlor und Brom) durchgeführt. Die erhaltenen wasserfreien als auch hydratisierten Verbindungen ...
Von neuen Li/Cl-Phosphinidenoid-Komplexen zuneuartigen funktionellen Phosphanyliden-Phosphoran-Komplexen
(2020-12-11)
Innerhalb dieser Arbeit wurden folgende drei unterschiedliche Fragestellungen der Komplexchemie behandelt: (1) Darstellung von Komplexen mit neuen dreigliedrigen heterocyclischen Liganden des N,P,E-Ringsystems (E = Bor, ...
Synthesis and reactions of Janus-type bis(NHCs), tuned by phosphorus bridges
(2021-02-15)
Due to our first attempts to synthesize P-functional bis(NHCs),[6] we were aware of a problem if bis(thiones) were used. Therefore, the idea emerged to use bis(selones) instead. Herein, the synthesis of the first tricyclic ...
Investigating 5-HT2A receptors - Development of a fluorescent 5HT2A receptor agonist and elucidation of the effects of St. John's wort extract STW3-IV, hyperforin and hyperoside on 5HT2A receptors

The Influence of Solvent Reorganization on Organocatalytic Reactions
(2021-04-07)
In the last decades N-heterocyclic carbenes have shown a certain potential as organocatalysts. In addition to the formation of regio- and stereoselective C-C coupling reactions, their scope of application includes the ...
In Silico Understanding of the Hydrogen Bond Network in Organic Solvent Mixtures
(2022-05-20)
In the framework of green chemistry, it is fundamental to further investigate the intermolecular interactions that define the dynamics and structure of liquids and their mixtures. Among those, the hydrogen bond in particular ...
