Associate members of HIPOLE Jena
“I have been working with colleagues at the HZB in the field of energy materials for many years. The association as a member of HIPOLE Jena now offers me the attractive opportunity to expand further this collaboration on a scientific but also institutional level and to leverage synergies between the materials chemistry in Jena and the HZB unique equipment infrastructure.”
Prof. Dr. Martin Oschatz
“I am excited about transferring our expertise in the field of polymer materials and their nanoscale structures to new fields of application as part of our collaboration with HIPOLE and the Helmholtz Association, while at the same time benefiting from the knowledge of new partners.”
Prof. Dr. Felix H. Schacher
“HIPOLE Jena brings together a unique combination of expertise in the areas of polymer science, advanced characterization methods and a strong focus on renewable energy. This has ideal synergies with the research activities in our group, which is why we are excited to work together on the next generation of clean energy technologies.”

In particular, we develop porous carbon materials, for example as electrode materials for batteries and supercapacitors, for the adsorption and electrochemical conversion of small molecules (e.g. nitrogen or carbon dioxide) as well as for light-driven water splitting or adsorptive water purification.
Based on materials with a defined chemical structure and tunable pore architecture, we aim for a more precise understanding of fundamental mechanisms in these applications. This means that materials can be tailored in advance in the future. Another core point of our research is the production of such high-performance materials via energy-efficient syntheses and from sustainable precursor compounds such as biological polymers

We are primarily concerned with the synthesis of polymers using living and controlled polymerization methods, as well as their structure formation in different environments. The focus is often on polyelectrolytes and polyampholytes and their behavior at interfaces. We also contribute expertise in the investigation of nanoscale structures using imaging methods or scattering techniques (light and X-ray scattering) and their modification using various methods.

We work on sustainable molecular catalysis for energy conversion and focus on (solar) light-driven processes (endowed CZS-junior professorship). We apply the concept of compartmentalization via biomimetic membranes, as well as light-induced energy and electron transfer, e.g. for catalytic water splitting and CO2 conversion. We design and synthesize tailored molecular organic and molecular coordination compounds. For mechanistic investigations, we apply steady-state and time-resolved spectroscopy (ns-microseconds, UV-vis).

My research is focused on new functional polymeric materials. In particular, self-healing materials are studied. Reversible polymers are utilized to achieve the restoration of mechanical damage and functional self-healing materials, which are capable to restore their function after a damage event (e.g., absorption after photooxidation), are studied. Furthermore, conjugated polymers for their use in solar cells are researched.

In our research, we develop novel data-driven techniques to solve real materials design problems across scale in an actionable way. We use machine learning models as navigation systems for the chemical space. We do this in close collaboration with experimental partners and by working on several themes that are key for progress in the field.

Since 2023 I lead a research group at Friedrich-Schiller-University Jena and since 2024 I am an associated member of HIPOLE Jena. Our research group focuses on the development of photocatalysts for the direct production of green hydrogen from solar energy.
To this end, we work with different polymer materials, such as conjugated polymers and carbon nitrides, to enable light absorption and catalysis, splitting water into hydrogen and oxygen. Our research aims to elucidate novel mechanisms to utilize solar energy for this reaction, applying these learnings for the development of efficient photocatalysts and preparing this technology for scale-up through the development of suitable photoreactors and processes.
