Electrochemistry and spectroelectrochemistry of organic electroactive materials
The team specializes in electrochemical and spectroelectrochemical analysis of organic low-molecular compounds as well as oligomers/polymers. The main aim of such analysis is to investigate the properties and suitability of the tested systems for further applications in (opto)electronics, but also to determine and understand the mechanisms of electrode reactions, including degradation processes, and to relate it with the structure of the molecule to enable the design of materials with the desired properties.
