New sulfenate sources for double pallado-catalyzed cross-coupling reaction: application in symmetrical biarylsulfoxides synthesis, and evidence of TADF properties. [PDF]

Tetrahydro-4H-thiopyran-4-one 1-oxide 1 and sulfinyl-di-tert-butylpropionate 2 were reported as sources of bis-sulfenate anion and applied in a double pallado-catalyzed cross-coupling reaction for the synthesis of symmetrical biarylsulfoxides, tolerating

Effect of the Imidazole π‐Extension on TADF Emitters in Electrochemiluminescence

Chemistry – An Asian Journal
AbstractAlready known molecules which exhibit good electrochemiluminescence (ECL) efficiencies and high photoluminescence quantum yields (PLQY) have been structurally modified in order to increase their performance. The followed strategy is to stiffen the structures to limit the rotational and vibrational freedom degrees and favour radiative decay ...

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.

The degradation mechanism of multi-resonance thermally activated delayed fluorescence materials

Nature Communications
1,4-Azaborine-based arenes are promising electroluminescent emitters with thermally activated delayed fluorescence (TADF), offering narrow emission spectra and high quantum yields due to a multi-resonance (MR) effect. However, their practical application

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 ...

Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing

Laser &Photonics Reviews, EarlyView.
Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

Structural and Spin–Orbit Coupling Synergy Enables Tunable Afterglow in Cytosine‐Based Hybrid Materials

Laser &Photonics Reviews, EarlyView.
Zero‐dimensional organic–inorganic hybrid materials (Cyt)2ZnX4·H2O (X = Cl, Br) were synthesized using cytosine (Cyt) and zinc halides, enabling effective regulation of room‐temperature phosphorescence (RTP) through halogen substitution in the inorganic [ZnX4]2− unit.
