Towards efficient deep-red TADF emitters for bright organic light-emitting diodes – BOOSTOLED

Submission summary

Organic Light-Emitting Diodes (OLEDs) are revolutionizing display market technology. Also, they are appealing for other applications, including lightweight and flexible devices operating at high brightness under low power. Yet, there are still key-challenges that need be tackled, e.g. efficient and robust, rare metal-free materials and suitable device engineering. The project BOOSTOLED aims at purely organic, thermally-activated delayed fluorescence-active (TADF) materials for efficient deep-red to NIR OLEDs for biomedical applications. The project challenges innovative donor-acceptor (D-A) systems that combine narrow bandgap, high photoluminescence quantum yield and balanced charge transport. BOOSTOLED will explore different material engineering strategies, including intra- and through-space TADF materials. Energy-efficient flexible/stretchable tandem OLEDs will be developed that can simultaneously achieve high external quantum efficiency >60%, brightness >10^5cd/m2 and long lifetime.
