Abstract

There has been a great deal of interest in developing new materials for the fabrication of light emitting diodes (OLEDs). We have prepared a range of intensely luminescent Ir(III) and Pt(III) complexes, which have found application in both monochromatic and white OLEDs. The role of the Ir and Pt in these complexes is to achieve efficient emission from the triplet excitons formed in the electroluminescence process. In my talk I will briefly discuss device architectural and materials choices that are made to improve efficiencies to their limits. Using this approach we have achieved internal efficiencies of nearly 100%. In addition to our work on monochromatic OLEDs, we have spent a great deal of time working with broadband, white emissive OLEDs. I will discuss the chemistry of these design of these devices as well.
