TADF Molecules:

TADF fluorophores are among the most promising technologies for organic light-emitting diodes (OLEDs). TADF stands for thermally activated delayed fluorescence. Metal complexes based on copper or even purely organic molecules can exhibit TADF properties. In addition to prompt fluorescence, these molecules also exhibit a delayed component. Prompt and delayed fluorescence together allow a theoretical internal quantum yield of 100%, making TADF molecules competitive with phosphorescent dyes.

Organic molecules and organometallic complexes can be specially designed to preserve the TADF character. Established approaches are twist-induced charge-transfer, through-spacer charge-transfer and multiresonance effect. All three approaches have been investigated for several years in the research group of Prof. Bräse. Therefore, this group offers a wide expertise in the large field of TADF fluorophores.

Metal-Complexes:

We are always looking for curios minds with a special interest in metalorganic chemistry. In our 3MET project „Cooperative Effects in Homo- and Hetero-Metallic Complexes” of the Deutsche Forschungs­ge­mein­schaft DFG (SFB/TRR 88) we are working on different metal complexes for the use in catalysis (B2) as well as on luminescent materials based on coinage metals (T1) for the use in organic light-emitting diodes (OLEDs). As metalorganic chemistry combines the synthesis of organic ligands and metal complexes a great variety of working tasks arises as well as for the analytical and (photo)physical characterization of the compounds. Are you interested? Please send us your application.

Materials:

In the research group of Prof. Bräse, building blocks for highly porous materials have been synthesized for a long time. This includes the preparation of functionalized linker molecules for metal-organic frameworks (MOFs, COFs) and the synthesis of rigid aromatic building blocks for purely organic networks. In collaboration with other groups, these materials are synthesized and characterized, and potential applications are tested. Prof. Bräse's group has many years of experience and successful publications with many other collaborators. Recently we are also working on the synthesis of polyaromatic compounds for the application in solar cells. Are you interested in a thesis/dissertation on this topic? You are welcome to choose one of the presented topics or get a more detailed insight into current research on materials at our listed research interests. Please contact the corresponding staff or Mr. Prof Bräse. We are happy to discuss your own topic requests.

Paracyclophane:

The [2,2] paracyclophane is a central molecule in the research of this group. It has been used for many years as a building block for the synthesis of a wide variety of complex structures. Our research is mainly based on the possibility to incorporate chirality and the spatial separation of functional groups. Currently, our research focuses on the synthesis of (chiral) (heterobi)metallic complexes based on paracyclophane and their application. Chiral paracyclophanes are also used in CVD polymerization. Furthermore, fluorophores are synthesized starting from the paracyclophane. Are you interested in working with this molecule or do you have an idea for a topic? Please contact the corresponding staff or Prof. Bräse to arrange a possible topic.

Natural proucts:

The synthesis of natural products, biologically active materials and peptides has a long tradition in this group. Many natural products have been obtained over the years. Currently, the total synthesis of natural products continues to be pursued in this group. The equipment of the group as well as the experience of our staff and Prof. Bräse offers a good basis for further successful syntheses. Furthermore, the synthesis and modification of peptoid structures is a present topic in this working group. Over the years, research has continued on biologically active as well as bioisosteric molecules and their effects on cells have been tested. If you are interested in working with natural products, biologically active molecules as well as the development of synthesis methods, you are welcome to contact Prof. Bräse to work out an appropriate topic.
