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, Volume 36, Issue 36, 4 May 2026.
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 ...

Degradation of Blue MR‐TADF OLEDs: Host‐dependent Effects of mCBP and MADN Revealed by Fragmentation Profiling

Advanced Optical Materials, Volume 14, Issue 17, 8 May 2026.
Degradation in blue MR‐TADF OLEDs originates from high triplet density caused by slow RISC. LDI‐TOF MS directly detects host‐ and emitter‐derived fragments, providing molecular insight into how triplet accumulation drives degradation in the emissive layer. ABSTRACT Blue organic light‐emitting diodes (OLEDs) employing multi‐resonance thermally activated

Multi‐Level Confinement Single‐Molecule Charge Transfer Activated PRET for Near‐Infrared Targeted Cell Imaging

Advanced Science, Volume 13, Issue 25, 4 May 2026.
The cascade supramolecular assembly of charge‐transfer arrays not only triggered a topological transformation from nanofiber to nanorod and vesicles, but also promoted single‐molecule phosphorescent resonance energy transfer, expanding phosphorescence emission at 500 nm to near‐infrared delayed fluorescence emission at 650 nm with a lifetime of 11.20 ...

Precise Vibration Decoupling and Matrix Rigidification: A Dual Locking Strategy for Highly Efficient Photoluminescence

Aggregate, Volume 7, Issue 5, May 2026.
This work presents a dual strategy for constructing high‐efficiency photoluminescent materials. At the molecular level, vibration decoupling is suppressed through space charge transfer chromophores, boosting fluorescence. At the aggregate level, rigid polymer matrices protect and stabilize triplet excitons, enabling efficient and colorful room ...

Carbon Dot Self‐Assembly: Bottom‐Up Fabrication, Morphological Evolution, Luminescence Regulation, and Advanced Applications

Aggregate, Volume 7, Issue 5, May 2026.
The self‐assembly of carbon dots, which enables precise control over their macroscopic architectures and collective properties, profoundly enhances their functionality. This review systematically summarizes the field through four key aspects—morphology control, luminescence modulation, assembly mechanisms, and advanced applications—and thereby offers a
