Photoelectron spectroscopy of 5,12-diazatetracene

Research output: Contribution to journalArticle


The electronic structure of 5,12-diazatetracene (DAT) has been studied in the gas phase by UV photoelectron spectroscopy and quantum chemical calculations. The comparison of DAT spectrum with the spectrum tetracene (TC) shows the shift of outermost π-ionizations towards higher ionization energies and the appearance of nitrogen lone pair ionizations in the second and third spectral bands. The difference between nitrogen lone pair ionization energies is smaller in DAT compared to diaza analogues containing up to three fused rings. The implications for semiconductor properties are discussed.
