General:

The redox potentials of the compounds synthesized by our group are important for the electronic properties, such as conductivity, photo- and electroluminescence and the stability against oxidation and reduction. The best method to determine the electrochemical data is cyclic voltammetry (CV) . Spectroelectrochemical investigations are carried out in organic solutions which are purifed by special methods. The CV gives information about electron transfers, such as possible consecutive reactions. A further electrochemical investigation method is spectroelectrochemistry (SEC) which gives information about the variation of the electronic structure at fixed potentials. In our group we use UV / Vis / NIR - spectroscopy in the range of 320 to 2000 nm. Typical electrochemical methods such as cyclic voltammetry and polarography characterize the electrode system and the electrolyte by potential, electric current and their time factor. However information on the structure of the compounds, such as their reaction products at specific potentials are only available through the combination of CV- and SEC- measurements.
