Description

Application

Purely organic thermally activated delayed fluorescence (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 m-ACSO2 is a promising TADF as solution-processable TADF blue emitter without the need of a host with a singlet–triplet energy gap (ΔEST) of 0.07 eV.

TADF Blue m-ACSO2 can be utilized as an emissive material in blue-emitting OLEDs. Its thermally activated delayed fluorescence properties allow for efficient harvesting of triplet excitons, resulting in enhanced device efficiency and reduced energy loss. By using the compound as an emissive material, it can contribute to the production of energy-efficient and long-lasting blue lighting devices.
