Structural and Photophysical Properties of Electro Luminescent Material and its Significance for Organic Light Emitting Diodes

This project aims to elucidate the connection between the molecular structure, the structure in solid bodies and the optoelectronic properties of OLEDs. A special emphasis is placed on the energetics and dynamics of the triplet state in Alq3 and materials derived therefrom. A better understanding of the photophysical processes is expected to permit a more efficient doping with phosphorescent colour pigments to increase the efficiency of OLEDs.
