Pyrimidine-Based Thermally Activated Delayed Fluorescence Emitters for Deep-Blue Organic Light Emitting Diodes

Organic light emitting diodes (OLEDs) used in displays and lighting have advanced display quality but still face issues such as low efficiency and short lifetimes, especially for blue emission. Thermally activated delayed fluorescence (TADF) provides an exciting solution for these challenges, yet there are still few examples of efficient blue TADF emitters. Highly efficient, stable deep blue TADF emitters will enhance OLED performance by improving colour purity, brightness, and lifespan. This will also reduce consumer turnover of electronics which are expensive to fabricate and can have negative environmental impacts upon disposal.
This research program will introduce eight efficient deep blue TADF candidates. The results will advance OLED technology, contribute to Canada’s digital technology goals, and foster the continued collaboration and transfer of knowledge between Canadian researchers and international colleagues.
