Time-resolved studies on isolated NTCDA and NDCA — •Thiemo Gerbich and Ingo Fischer — Institut für Physikalische und Theoretische Chemie, Universität Würzburg, Am Hubland, D-97074 Würzburg, Germany

In spite of numerous applications of 1,4,5,8-Naphtalene-tetracarboxylic-dianhydride (NTCDA) in organic electronics such as thin-film-transistors, studies of the electronic structure and the dynamics of the isolated molecule are still rare. In our experiment we apply picosecond time-resolved photoionization spectroscopy and observed NTCDA in a pulsed molecular beam. We present the first results of the electronic structure and show some time-resolved transients. In addition we present measurements of 1,8-Naphtalenedicarboxylic-anhydride (NDCA) which appears as a fragment of NTCDA and shows as well a picosecond dynamic.
