Development of Narrow Band Blue and Red Emitting Macromolecules for Solution-Processed Solid State Lighting Devices

ended

This project targets the development of solution-processable narrow-band thermally activated delayed fluorescence compounds that will be employed in low-cost solution-processed solid-state lighting devices. Solution-processed organic light-emitting diodes (OLEDs) and light emitting electrochemical cells (LECs) will be fabricated from these materials. The stringent design criteria will be met by adapting multi-resonant thermally activated delayed fluorescence materials to be compatible with solution processing techniques. Using the proposed design it is expected that narrow emission (FWHM of 25-30 nm) and high efficiency can be maintained, which would represent a real advance in both solution-processed OLEDs and LECs. This project will specifically develop solution-processable blue and red narrow band emitting TADF materials as these are both essential for displays and lighting and whose performance in current state-of-the-art OLEDs and LECs remains sub-optimal.
