Revealing Mechanofluorochromism and Intricate Long‐lived Decay Pathways in Keto‐Coumarin‐Based Molecular Crystals

Advanced Optical Materials, Volume 14, Issue 35, 18 September 2026.
Donor–acceptor organic emissive materials show great promise in cutting‐edge optical applications. Herein, the photophysical properties of two keto‐coumarin organic materials are studied in detail. Both show mechanofluorochromism, but a diphenylamine donor derivative exhibits intricate decay pathways in the crystal form, including decays ranging from ...

Water‐Enabled Ultralong Full‐Color Organic Phosphorescence in Hydrogen‐Bonded Frameworks for 4D Encryption and Bio‐Imaging

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Water‐induced quenching challenges organic RTP materials, but a counter‐intuitive strategy employs HOF to encapsulate carbonyl guests, where water functions as a structural reinforcer. This achieves water‐enhanced ultralong RTP with full‐color emission (blue to deep red), overcoming intracellular quenching for high‐signal cellular imaging, alongside 4D

Efficient Polaron Recombination and Fast Energy Transfer in a Deep Blue Phosphorescent Pt(II) Complex via Covalently Fused p‐Type Host

Advanced Science, Volume 13, Issue 53, 24 September 2026.
Achieving high‐efficiency deep‐blue phosphorescent OLEDs is limited by intermolecular kinetic bottlenecks. We overcome this using a single‐molecule fused emitter architecture, Pt‐SP‐tCz, combining a p‐type host and Pt(II) dopant. This design enables zero‐radius intramolecular energy transfer (ZRIET) and a novel ZETPLEX mechanism.

Integrated Optoelectronic Model to Predict the External Quantum Efficiency of Single‐Layer TADF Organic Light‐Emitting Diodes

Advanced Electronic Materials, Volume 12, Issue 18, 21 September 2026.
An experimentally validated optoelectronic device model is presented to describe the efficiency and roll‐off behavior of single‐layer TADF OLEDs. By coupling charge transport, exciton dynamics, and optical outcoupling, the model reproduces the External Quantum Efficiency (EQE) across different emission layer thicknesses and temperatures, offering ...

Research Progress of Room‐Temperature Phosphorescence Materials Based on Reversible Bonding Interactions

Aggregate, Volume 7, Issue 9, September 2026.
This review summarizes the latest progress of RTP materials with self‐healing and shape–memory functions, in which reversible bonding interactions are the key points. With the careful discussions of the typical strategies and representative works, the intrinsic relationship between dynamic bonding interactions and RTP property is well revealed. Finally,

Color‐Tunable Organic Room‐Temperature Phosphorescence From Single‐Luminophore Aggregation in Polymer

Aggregate, Volume 7, Issue 9, September 2026.
A single‐luminophore design featuring a planar π‐conjugated carbazole core and sterically hindered side groups affords a distinctly low critical aggregation concentration. Concentration‐controlled evolution from monomers to π–π stacked dimers enables continuous room‐temperature phosphorescence color tuning from green to orange–red with lifetimes ...

Triplet Acetone Generation by Pseudoperoxidase Activity of Myoglobin: Structural Damage and Quenching

Luminescence, Volume 41, Issue 9, September 2026.
Ferrimyoglobin pseudoperoxidase activity was demonstrated during isobutyraldehyde oxidation, yielding electronically excited triplet acetone and inducing structural damage. Sorbates and 9,10‐dibromoanthracene‐2‐sulfonate exhibited protective effects.

N‐Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions

Chemistry – A European Journal, Volume 32, Issue 33, 1 September 2026.
Acridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.

Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

FlexMat, Volume 3, Issue 3, Page 359-367, September 2026.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

FlexMat, Volume 3, Issue 3, Page 368-381, September 2026.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.
