Research outcomes 

The team has published over 100 scientific papers, participated in more than 10 international projects. We have collaborated with leading research groups from UK, Japan, USA, Spain, France, Switzerland as well as with industrial partners “Energenas”, “Ledigma”, “Fine Synthesis” in developing novel organic compounds, new synthesis and purification technologies.

 

Resources

The team owns organic optoelectronic technology facilities for solution processing, vacuum thermal evaporation, optical characterization of organic compounds and thin films, device testing and encapsulation. We have the third world’s largest inert-atmosphere glovebox system installed by MBraun. There is an additional characterization infrastructure based on scanning probe and electron microscopes, ultrafast pump-probe spectroscopy and quantum efficiency evaluation systems.

Moreover, the research group has strong relations with the experts in organic synthesis. That relationship ensures continuous supply of high-quality organic compounds, which are necessary for studying various physical processes as well as for production of high-performance optoelectronic devices. The synergy between physics and chemist groups facilitates discovery and the in-depth understanding of the novel phenomena in organic materials, and accordingly paves the way for high impact scientific publications.
