Abstract
- Herein, we report a fluorene-bridged double carbonyl/amine-based MR TADF emitter DDiKTa-F, formed by locking the conformation of the previously reported compound DDiKTa. Using this strategy, DDiKTa-F exhibited narrower, brighter, and red-shifted emission. The OLEDs with DDiKTa-F emitted at 493 nm and showed an EQE<subscript>max</subscript> of 15.3% with an efficiency roll-off of 35% at 100 cd m<superscript>−2</superscript>. [ABSTRACT FROM AUTHOR]
