Project description
Seeing red: expanding the spectrum of advanced organic LEDs
Organic light-emitting diodes (OLEDs) are now widely used in consumer electronics displays, where they enable lighter and thinner devices that use less energy than conventional LEDs. Thermally activated delayed fluorescence (TADF) emitters have many advantages over OLEDs. These include 100 % internal quantum efficiency and avoidance of potential shortages of ordinary fluorescent and phosphorescent compounds. However, so far, they have a limited spectral range. With the support of the Marie Skłodowska-Curie Actions programme, the DR NIR TADF-OLEDs project is planning to open the door to deep-red and near-infrared TADF OLEDs, harnessing a novel class of purely organic TADF-emitters with aggregation-induced emission properties that have not yet been investigated.
Objective
Thermally activated delayed fluorescent (TADF) emitters offer an exciting opportunity to produce efficient organic light-emitting diodes (OLEDs) by overcoming the spin-statistics limit of fluorescent emitters. Although, TADF-OLEDs have proven to be very successful in the visible spectral region, the development of efficient TADF emitters remains challenging for the deep-red (DR, 650-700 nm) and Near-Infrared NIR (< 700 nm) region due to significantly slower radiative decay rates and faster non-radiative decay rates. Such DR/NIR emitting OLEDs can enable new applications in bioimaging, photodynamic therapy, night vision technology, information-secured displays, and optical communication. We propose to develop efficient and inexpensive DR/NIR OLEDs based on purely organic TADF-emitters. Our design consists of a yet unexplored aggregation-induced emission (AIE)-active boron diiminate (BDI) electron acceptor coupled with suitably strong dendritic electron donors. The use of highly efficient AIE-active emitters will significantly enhance the brightness of the emitter by suppressing non-radiative decay, thereby leading to a much-improved efficiency in the device.
