Photoelectron spectroscopy study of anthracene anions in gas phase — •Kevin Schwarz, Aghigh Jalehdoost, and Bernd v. Issendorff — Institute of Physics, University of Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg, Germany
Organic semiconductors like anthracene (C14H10) show interesting properties and keep being of interest across science and technology. They are used, for instance, in organic solar cells. To get a better understanding of those molecules they are investigated in the gas phase by anion photoelectron spectroscopy (PES) to gain knowledge on the different involved electronic and vibrational modes of the molecules, especially on electronic relaxation processes giving information about the dynamics within the molecules. Furthermore, temperature-resolved studies are of high interest due to changes in the vibrational modes accessible to the clusters, so to address those measurements and also to increase the resolution of the spectra in general a radio frequency ion trap will be added into the setup.
