Research

Our institute focuses on crystallographic methods beyond routine structure determination of inorganic compounds. One aspect is the detailed study of reaction mechanisms and structure/properties-relationships, focussing on a broad range of inorganic chemical problems involving materials, network compounds, molecular organometallic compounds and pharmaceutical products. Another aspect is method development within the field of crystallography. Modern techniques of experimental electron density determination and analysis are expanded and directly linked to the respective chemical projects.

The experimental determination of the electronic structure of compounds containing heavy elements with relativistic effects is of key interest and is investigated in three different ways: lone pair interactions of heavy elements in network compounds (AG Gesing), bonding properties of heavy elements in molecular compounds (AG Beckmann) and extraction of relativistic effects from the electron density (AG Grabowsky). This leads to an improved understanding of structure/properties-relationships, which is of fundamental importance in the development of novel materials and is therefore directly connected to the "MAPEX Materials and Processes" center of the University of Bremen.

Beckmann Group

Organometallic chemistry of the light and heavy main group elements is investigated in its complete range, focussing on bonding and material properties by investigating the physically and spectroscopic nature of novel compounds. The development of new compounds with direct application (such as catalysts) are also of key interest to the group.

Gesing Group

The group is interested in temperature-dependent structure property relations of oxides, especially of compounds with activity lone electron pairs or small framework structures. Structural phase transitions,
template-framework interaction, separation of thermal displacement and structural distortion or thermochromic behavior are as well of interest as photonic and (photo-)catalytic effects. Additionally we are dealing with the modeling of thermal expansion behavior and the corresponding model development on one hand and structure refinements and spectroscopic characterization from nano- to single crystals on the other hand.

Grabowsky Group

We are a junior research group funded within the Emmy Noether scheme of the German Research Foundation. We commenced our work at the University of Bremen in summer 2014. Our main field of research is method development in crystallography and application of the new methods to inorganic and bio-organic questions.
