that can be synthesized, offers the possibility of finding
the right materials for every application. Prof. Karl Leo is an internationally recognized researcher
in condensed matter physics. Among his achievements
are the first observations of coherent electronic dyna-
mics in solids and pioneering work on organic semicon-
ductors. Many of these technologies were successfully
transferred to spin-off companies like Novaled and
Heliatek. His main current research interests are novel
organic electronic devices (Organic Devices and Structures
group) and organic sensors (Organic Sensors group).

Prof. Leo has been rewarded with the Leibniz Award
2002 of the DFG, the German Future Award 2011 of the
German President and the European Inventors Award
2021 of the European Patent Office.
