Research

Bunz group

Prime focus of the research of the Bunz group is the synthesis, fabrication and characterization of acenes, azaacenes and azaarenes as hole and electron transporting materials for application in electronic devices such as thin-film transistors or organic light-emitting diodes.

DeKieviet group

The research of the group of Dr. M. DeKieviet focusses on the structure and dynamics in and at the outermost surface layer of advanced materials. The studies include the characterization of well-ordered thin organic films, with particular emphasis on interplay between the surface structure and the dispersion of the corresponding phonon modes.

Dreuw group

The group of Prof. Dreuw develops quantum chemical ab initio methods to describe molecular properties of organic molecules embedded in molecular environments. A particular focus is put on excited electronic states and energy transfer processes. But also methods for the efficient and accurate calculation of ionization potentials and electron affinities being related to charge transfer processes are developed.

Kivala group

The focal point of our research program is the synthesis and study of heteroatom-doped polycyclic aromatic scaffolds with the aim to i) investigate the influence of interior heteroatoms on their fundamental structural, electronic, and materials characteristics and ii) apply the resulting compounds as active materials in organic optoelectronic devices.

Klingeler group

The team's activities include synthesis of new materials as well as investigation of magnetic, electronic and structural properties. The focus in materials research includes (1) metal-organic coordination compounds and magnetic molecules, (2) Carbon-based nanomaterials and hierarchically structured nanocomposites, (3) functional oxides (e.g., multiferroics) and, (4) carbon-wrapped nanomagnets.

Mastalerz group

Prof. M. Mastalerz research program focuses on the synthesis of nanosized cage and ring compounds with an emphasis on shape-persistent covalently bound structures, by dynamic covalent chemistry (DCC). The obtained functionalized compounds have defined and precisely confined interior space, which can be used to host guest-molecules of different sizes or for gas sorption.

Motzkus group

The Motzkus group runs and scientifically leads the fs-laser lab at the CAM. The current main focus of our work is the investigation of ultrafast dynamics of Singlet Fission (SF). Under favorable conditions, SF converts a pair of molecules residing in the ground and in the first-excited singlet states (S₀S₁) into a pair of triplet states (T₁T₁).

Müllen group

Our research is mainly focused on the synthesis, characterization and application of nanomaterials for optoelectronic devices. We are particularly interested in charge transport, excitation transfer and light-matter interaction in these materials. We use a wide range of experimental techniques from chemical synthesis, optical spectroscopy (e.g. fluorescence spectroscopy, Raman microscopy etc.), surface characterization....

Na Liu group

The Liu group works in the field of nano-optics, where light is guided, focused, concentrated, and manipulated in areas and volumes that are comparable or smaller than the wavelength of light. This is achieved through nanostructuring of dielectrics as well as metals. Their research encompasses the development of bottom-up DNA nanoengineering, and the development of functional nano-plasmonics.

Pfannmöller group

Pucci group

The Pucci group is doing research on the relationship between nanostructure production details and physico-chemical properties. Metallic nanostructures with a defined design have been prepared with the help of electron-beam lithography. The analysis of the systems mainly is done with various infrared (IR)-spectroscopic methods, including ellipsometry, far-field microscopy, and, recently, scanning-nearfield microscopy (with tiny tip).

Schröder group

Skibbe group

The Skibbe group uses High Resolution Electron Energy Loss Spectrsocopy (HREELS) to investigate the role of defects at interfaces of metals to organic molecules as well as surface properties.

Vaynzof group

A. Winnacker (Honorary Director)

The scientific work of Albrecht Winnacker focused originally on the properties of point defects in solids in general and compound semiconductors in particular. Later crystal growth of new compound semiconductors like SiC and AlN and investigation of their physical properties and growth behavior was added,...

Zaumseil group

The Zaumseil group is mainly interested in carbon-based materials (single-walled carbon nanotubes and organic semiconductors) for a wide range of optoelectronic devices. The focus is on charge transport in thin film transistors but also on strong light-matter interaction for light emission and detection in the near-infrared.
