Application

Purely organic TADF emitters can recruit both singlet and triplet excitions for light emission and hence achieve 100% internal quantum efficiency (IQE). Additionally, purely organic TADF emitters avoid the problems associated with the use of heavy-metal-based organometallic complexes.
Bright, deep blue and stable emitters for OLEDs are grand challenge on OLED design at the moment. In this context, our TB-P3Cz is a promising TADF as solution-processable TADF blue emitter without the need of a host with a singlet–triplet energy gap (ΔEST) of 0.113 eV.
TADF blue materials can be investigated for their potential in organic light-emitting diodes (OLEDs). TADF emitters exhibit efficient utilization of both singlet and triplet excitons, resulting in enhanced device efficiency and reduced energy loss. It can is suitable in R&D studies of optoelectronic devices that require blue emission within the visible spectrum.
