Design of multiresonance thermally activated delayed fluorescence materials for high-performance organic light-emitting diodes

A grand challenge in emitter design for OLEDs is to develop bright materials that emit at the industry-targeted deep blue color point and use translates into efficient and stable blue devices. This requires the emitter to be narrowband emissive in the deep blue, be very bright, and be able to have short exciton lifetimes to mitigate undesired biexcitonic degradation pathways like singlet-triplet and triplet-triplet annihilation. In this presentation, I will discuss our recent efforts to towards the design of multiresonant TADF emitters that meet all of these design criteria simultaneously, and demonstrate their potential in OLEDs.
