Project description

Narrow-band light emitters and solution processability for next-generation displays and lighting

Organic light-emitting diodes (OLEDs) and more recent light-emitting electrochemical cells (LECs) are enabling technologies for modern display and lighting applications. However, they are currently challenged by broad emission spectra. Narrow-band light-emitting materials and molecules are necessary for crisp, vivid colours. Further, low-cost fabrication methods are required, among which are solution-processing techniques. These are currently compatible with emerging LEC technologies, but solution processing of OLEDs is uncommon. With the support of the Marie Skłodowska-Curie Actions programme, the NarrowbandSSL project is developing solution-processable narrow-band fluorescence compounds that will be employed in solution-processed OLEDs and LECs to produce low-cost solution-processed solid-state lighting devices.

Objective

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.
