Abstract
One approach to increase the overall performance of organic light emitting devices is to separate the light-emitting volume from the ones which are as signed to charge injection or transport. The electronic properties of model heterocyclic compounds, namely low molecular phenylquinoxalines and relate d derivatives, for electron transport layers have been investigated by Ultr aviolet Photoelectron Spectroscopy. The ionization potentials of these mate rials have been determined.
