o‐Carborane‐based multi‐resonance thermally activated delayed fluorescence emitter exhibits highly efficient and multifunctional electroluminescence

FlexMat, EarlyView.
By strategically incorporating boron/nitrogen multi‐resonance (B/N‐MR) core into the o‐carborane unit, perfect exciton utilization can be achieved as well as exhibiting stimuli‐responsive properties. The resulting DBN‐oCb‐based organic light‐emitting diode (OLED) demonstrated an impressive external quantum efficiency of 22.3%, the highest reported for ...

Graphene oxide/exfoliated black phosphorus van der Waals heterojunctions for PEDOT:PSS‐free‐based organic light‐emitting diodes achieving excellent electroluminescence performance

FlexMat, EarlyView.
A novel two‐dimensional heterojunction assembled from graphene oxide and exfoliated black phosphorus via van der Waals interactions is proposed to replace widely used poly(3,4‐ethylenedioxythiophene)‐polystyrene sulfonate for efficient hole injection layer in organic light‐emitting diodes, achieving impressive electroluminescence performance.

Carbonyl lock enables multi‐resonant organoboron framework with substantially enhanced spin‐flip and reduced emission bandwidth

FlexMat, EarlyView.
Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...
