| Abstract | Organic light emitting diodes (OLEDs) require an emissive electroluminescent layer of an organic semiconductor material located between two electrodes, where at least one of the electrodes is transparent. Such devices are revolutionising display technologies, with the production of flexible and fully transparent devices possible. Devices that emit circularly polarised electroluminescence (CPEL) should have vast translational potential in photonic technology, such as highly improved LCD backlighting, colour-image detection and stereoscopic displays, optical communication, and quantum computing, however to date the problem of directly generating CPEL has not been solved. The goal of this research is to use intrinsically chiral, conductive and luminescent small molecules as electroluminescent layer in OLEDs, in an attempt to demonstrate efficient CPEL. Such work would have significant impact on current knowledge, which could be exploited in a number of translational areas. Taking alternative LCD backlighting as one example of the exploitation of this work, current technologies rely on polarising filters that effectively cut out 75% of the light used in these displays. Combined with absorption by the colour filters and at device interfaces, only 4% of the light used is transmitted. The use of a polarised light source, coupled with tuneable colour components would remove this need, thus leading to significantly more energy efficient displays, with a dramatically lowered carbon footprint | |
