Using the smart matrix approach to enhance TADF-OLED efficiency and lifetime

Using the smart matrix approach to enhance TADF-OLED efficiency and lifetime

Objective

The European Training Network TADFlife will train a cohort of young PhD scientists within a multidisciplinary research program conceived from a simple industrial need, high performance blue OLEDs which also have long lifetime. This is not an easy problem to solve, as although OLEDs are now ubiquitous in phone and TV displays, the blue pixels still operate far below the performance and efficiency of the red and green to achieve acceptable lifetime. TADFlife will follow a new approach to solve this problem using the latest generation of OLED materials, thermally activated delayed fluorescent (TADF) emitters. Through a device simulation development program, which incorporates a high degree of basic photophysics input, predictive models of TADFOLED performance and lifetime will be built and used to design new TADF emitters and hosts which overcome the degradation pathways identified from the model predictions. These new materials will then be synthesised. By introducing the concept of the smart matrix, the complex guest host interactions of TADF materials will be included and used to optimise emitter orientation to maximise light out-coupling from devices. Quantum chemistry will use the photophysics results to direct new materials design in tandem with the model predictions. Taking this dual approach, we believe will lead to solutions so far unobtainable for OLEDs. This highly interlinked program gives a fantastic opportunity for the brightest young chemists, spectroscopists, theoreticians and device physicists to work together, learn complimentary skills that will be in high demand from European OLED industries. Leading experts will give courses on core scientific skills along with soft skills and international secondments will be offered, all to properly prepare them for their future careers. They will be part of a network answering a real industrial need and help to secure the future of our European OLED industries in the global OLED materials arena.
