Abstract

The performance of organic light‐emitting diodes based, for example, on poly(p‐phenylenevinylene) could be more easily optimized on the basis of a thorough knowldge of the energies of the electron affinities and the ionization potentials of the materials. Here, results from UV‐photoelectron spectroscopy are presented which allow the determination of the absolute binding energies of the occupied molecular orbitals of oligo‐PPV. These results are compared with values calculated using semiempirical methods.
