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 ...

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 ...

Rigid polymer matrix enables direct red afterglow from rhodamine dyes without energy transfer

FlexMat, EarlyView.
This work presents a universal and facile strategy to achieve direct red room‐temperature phosphorescence from commercial rhodamine dyes by harnessing the superior rigid confinement of a novel phosphorus‐containing polymer (DOBP), effectively bypassing the complex TS‐FRET process.

Boosting the Photoluminescence of Au@Cu12 Nanoclusters via Strategic Fluorine‐Atom Ligand‐Shell Engineering

Journal of the Chinese Chemical Society, EarlyView.
The photophysical performance of gold‐doped copper‐rich nanoclusters can be tuned by surface functionalization. Subtle ligand modification enhances intermolecular interactions, thereby reducing nonradiative decay and markedly improving photoluminescence. Comparative photographs and quantum yield values (Φ = 55% vs.
