Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Regioselective Oxidative Oligomerization of 2‐Tert‐Butylpyrene Toward Structurally Defined Oligomers and Their Application in Organic Light‐Emitting Diodes

European Journal of Organic Chemistry, Volume 29, Issue 36, 24 September 2026.
Treatment of 2‐tert‐butylpyrene with Cu2+ afforded structurally well‐defined pyrene oligomers, up to the 13‐mer. Single‐crystal X‐ray diffraction, spectroscopic analyses, and computational studies were conducted to evaluate the properties of the resulting oligopyrenes.

Machine‐Learning‐Guided Discovery of Boron‐Free Narrowband Blue Thermally Activated Delayed Fluorescence Emitters

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
A data‐driven discovery engine—exhaustive enumeration of carbazole‐containing polycyclic aromatic hydrocarbons (Cz‐PAHs) followed by machine learning—identifies boron‐free, narrowband blue thermally activated delayed fluorescence emitters for organic light‐emitting diodes (OLEDs).
