Harnessing the Orientation of Columnar Discotic Liquid Crystals for Narrowband Blue Emission with Enhanced Out‐Coupling Efficiency Toward Improvement of SP‐OLEDs Performance

Advanced Functional Materials, EarlyView.
Solution‐processed OLEDs containing discotic liquid‐crystalline MR‐TADF emitters are reported. Supramolecular self‐assembly induces homeotropic columnar alignment, enforcing preferential horizontal orientation of the emitter transition dipole moment in spin‐coated films, which leads to an enhancement in the device light outcoupling efficiency while ...

Revealing the spin–vibronic coupling mechanism of thermally activated delayed fluorescence

Nature Communications, 2016
Knowing the photophysics of thermally-activated delayed fluorescence (TADF) is crucial when designing organic light emitting diodes. Here the authors show that spin orbit coupling in TADF materials is described by a second order vibronic coupling ...

Thermally Activated Delayed Fluorescence in Phase‐Separated Nanostructures

Advanced Functional Materials, EarlyView.
A supramolecular, phase‐separation driven strategy yields charge transfer (CT) complexes from alternating electron‐deficient pyromellitic diimide and electron‐rich 4,5‐dibromoveratrole. The resulting CT complexes self‐assemble into lamellar nanosheets with nanometer‐sized domains that exhibit thermally activated delayed fluorescence (TADF) at room ...
