Research progress in photo‐controlled radical involved luminescence materials

FlexMat, EarlyView.
This review systematically dissects radical generation mechanisms, triplet‐exciton photophysics, material design strategies, and cutting‐edge applications in smart encryption, environmental sensing, and 3D printing. Abstract In recent years, photo‐controlled radical room‐temperature phosphorescent (RTP) materials have shown significant application ...

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.

Synergistic Effects of Fuel Components on Aromatics Formation in Combustion: A Review

Applied Sciences
Aromatics, especially polycyclic aromatic hydrocarbons (PAHs), are important combustion pollutants known to be carcinogenic and mutagenic and are also precursors of soot and, consequently, combustion-generated particulate matters that can significantly ...

Pyridine‐dicarbonitriles acceptor engineering in multi‐resonance thermally activated delayed fluorescence with hybridized short‐ and long‐range charge transfer for high‐performance electroluminescence

FlexMat, EarlyView.
Pyridine‐dicarbonitrile units integrated into a multiple‐resonance core engineer the excited state through cooperative short‐range charge transfer (SRCT) and long‐range charge transfer (LRCT), thereby enhancing the spin‐flipping process. Abstract Multi‐resonance (MR) thermally activated delayed fluorescence (TADF) materials exhibit narrowband emission ...

Diboron‐Embedded Heteroacenes With Systematically Varied Central π‐Skeletons and Fusion Modes

Helvetica Chimica Acta, EarlyView.
We synthesized diboron‐embedded acenes and revealed that fusion mode governs electronic properties, whereas molecular symmetry dictates crystal packing. One C2v‐symmetric isomer forms a uniform columnar π‐stacked array. ABSTRACT Diboron‐embedded heteroacenes with systematically varied central π‐skeletons and fusion modes were synthesized via one‐pot ...
