Emission Tuning of Group 13 DPP‑ Pincer Complexes via the Heavy Atom Effect of the Metal Ion and the Halide Ligands

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The complete series of all nine variations of complexes (DPP)MX2 (DPP = 2,5‐di(pyridin‐2‐yl)pyrrolide; M = Al, Ga, In; X = Cl, Br, I) reveals that the heavy atom effect of both the metal ion and the halide ligands promote ISC, giving rise to dual fluorescence and phosphorescence emission at 77 K. We report on the synthesis, structural characterization,

The Effect of Regioisomerism on the TADF Properties of Organic Dyes

ChemistryEurope
The properties of thermally activated delayed fluorescence (TADF) chromophores are highly dependent on the molecular design. The choice of the donor (D) and acceptor (A) group are as important as the choice of the π‐linker and the substitution positions.

Tetracyclic π‐Extended Multi‐Resonant TADF Emitters for Green PSF‐OLEDs With 37.7% EQE and BT.2020‐Compatible Top‐Emitting Devices

Advanced Functional Materials, Volume 36, Issue 79, 1 October 2026.
Ultra‐narrow green multi‐resonance thermally activated delayed fluorescence emitters have been developed by linear π‐extension strategy using tetracyclic naphtho[2,3‐b]benzofuran unit. The resulting phosphorescence‐sensitized OLEDs achieve a maximum external quantum efficiency of 37.7% in the bottom‐emitting architecture, while the complementary top ...

Elucidating the Key Role of Phosphorescent Sensitizers in High‐Performance, Long‐Lifetime Hyperphosphorescent Organic Light‐Emitting Devices Based on a Multi‐Resonance Thermally Activated Delayed Fluorescence Emitter

ChemPhotoChem, Volume 10, Issue 10, October 2026.
In hyperphosphorescent OLEDs, the carrier‐trapping characteristics of each phosphor and the asymmetric carrier mobility of the host material are suggested to influence the emission zone distribution, which is closely associated with operational lifetime, leading to an up to eightfold improvement in stability with Ir(ppy)3.

Conformational Control of Excited‐State Properties in Ortho‐Linked Triarylamine‐Based Donor–Acceptor Conjugates

ChemistryOpen, Volume 15, Issue 10, October 2026.
Highly blue emissive ortho‐triarylamine–acceptor (benzonitriles or cyanopyridines) conjugates are rapidly synthesized by bromine–lithium exchange borylation–Suzuki (BLEBS) sequence. Cyclic voltammetry reveals dimerization processes. Photophysical properties display stimuli‐responsive properties revealing them as promising emitters.
