Oberflächenstrukturen modulierter Systeme - Darstellung von regelmäßig angeordneten, polaren Nanodomänen mittels Piezoresponse Force Microscopy
(2020-07-23)Piezo force microscopy has been used to visualize nanoscaled surface charge density waves in a modulated ferroelectric system for the first time. Those self-organized structures are found in incommensurate systems close ... -
Ammonia stabilized Carbanions
(2018-01-17)This thesis examines the solvation of alkali metal cyclopentadienyl derivatives (Cp, CpMe, Cp*, indenyl, fluorenyl) in liquid ammonia as well as in solutions of ammonia in polar aprotic solvents. The degree of solvation ... -
Assessment of Single Crystal X-ray Diffraction Data Quality
(2017-03-13)This PhD thesis focuses on single crystal X-ray diffraction data quality, the handling of systematic errors during data collection and the appropriate modelling of experimental charge density distributions. The development ... -
Charge Density Analysis of Low-Valent Tetrels
(2016-02-11)This thesis deals with the bonding situation of low valent tetrels. More precisely an experimental charge density study of the silylone (cAACcy)2Si was carried out in order to investigate whether the bonding in this new ... -
Data Quality Bench-Marking for High Resolution Bragg Data
(2015-03-05)The thesis deals with data quality bench-marking for high resolution Bragg data. It compares and evaluates Bragg data from various radiation sources and different detection types. Two different small molecules containing ... -
Aggregation Study on Lithiated Five-membered Heterocycles – Towards the Pentuple Ion
(2014-01-30)The main work of this thesis focuses on the elucidation of the aggregation of 2-thienyllithium, methyl-substituted 2-thienyllithium and 2-furyllithium in the solid state and in solution. The addition of an adequate donor ... -
Charge Density Distribution in Low-Valent Tetrels
(2013-05-22)The scope of this work was the analysis of the electron density of low valent tetreles. For silicon and carbon-containing compounds. Especially low valent silicon compounds are of great interest because their synthesis has ...
