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 ...

Counter‐ion modulation: A facile approach toward quenching‐resistant multi‐resonance emitters for efficient narrowband electroluminescence

FlexMat, EarlyView.
Quenching‐resistant carbocation‐based multi‐resonance emitters are developed via a facile counter‐ion modulation strategy, giving much narrowed emission bands under high doping concentrations, and greatly improved device efficiency for solution‐processed narrowband OLEDs by simply increasing the size of counter ions.

Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

FlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.
