Paper Abstract

The relation between chemcial structure and functional properties of low-molecular and polymeric conjugated organic materials is discussed with respect to their use in organic light-emitting devices. Examples for emissive and for hole and electron transporting/injecting materials are given. The peculiarities of some nitrogen-containing heterocyclic compounds and their use as electron transporting/hole blocking materials are discussed in more detail. Results of an investigation of the valence electronic structure of a heterocyclic model compound (phenyloxadiazole derivative) at the interface to an inorganic conductive substrate are discussed in comparison to the interface between organic semiconductor/conductive inorganic electrode material as prominent in OLEDs. A short outlook towards future development is given.
