Abstract

Printed organic electronics is an emerging technology which attracts a lot of interest due to very broad range of possible applications. However in spite of very intensive reasearch carried out since several years in academic and industrial laboratories, there are still many unsolved problems hindering implementation of this new technology. Concerning printed organic light emitting diodes (OLEDs) among different obstacles two have fundamental meaning – low efficiency and poor solution processability. In this work we will present how one increase efficiency of electroluminescence by emplying triplet excited states using as the emitters new iridium complexes, and how one improve processability of the emissive layers by means of host-guest approach with ambipolar polymer as the host matrix.
