In General. In the Eisele group, our research focuses on the fundamental science of self-assembled nanostructures. We are passionate about elucidating light-matter interactions at the nanoscale, with particular emphasis on the complex interplay of structural and optical properties. In our group, we bring together Materials Research and Physical Research approaches. Our research unites
Experimental Investigations (Spectroscopy & Microscopy/Nanoscopy)
We are particularly interested in fundamental research with potential future applications, especially in the areas of renewable energy, health, and national security. Our research comprehensively combines different disciplines such as engineering, chemistry, physics, material science, and biology.
Specifically. In our lab, we synthesize/create and investigate artificial model systems for light-harvesting (both in solution and on solid substrates) in order to elucidate the fundamental processes that govern nature’s highly efficient photosynthetic masterpieces. Instead of improving the efficiency of current light-harvesting devices, our aim is to learn from nature’s design principles in order to inspire the creation of entirely new architectures that can operate both efficiently and robustly. Our group aims to contribute to a better understanding of energy and electron transport processes in nanoscale systems, which is vital to making new breakthroughs in the development of opto-electronic applications such as photovoltaic devices.
Materials Synthesis in Our Chemistry Laboratories. We create well-defined model systems in solution and on solid substrates. Our preparation methods include microfluidic techniques using low pressure syringe pumps from CETONI GmbH. We are fascinated by the collective phenomena found in self-assembled nanoscale systems such as supra-molecular assemblies (Frenkel exciton systems), semiconductor nanostructures (Wannier exciton systems), metallic nanostructures (plasmonic systems), and the organic/inorganic hybrid materials derived from these nanosystems.

Experimental Investigations in Our Nano-imaging and Spectroscopy Laboratory. One of the most challenging aspects of studying self-assembled nanoscale systems is the frequently observed heterogeneity in morphological, structural, and optical properties in ensemble samples. Therefore, a pivotal step to characterize and study self-assembled systems is to apply methods that allow for study of both the ensemble in solution and individual objects. Therefore, we investigate our model systems by employing a comprehensive set of research tools—experimental methods that embrace microscopy and nanoscopy techniques—including Near-field Scanning Optical Microscopy setup from WITec GmbH—combined with steady-state and time-resolved spectroscopy methods including Transient Absorption (TA) spectroscopy.
