Changing N^C^O to C^N^O Coordination in Cyclometalated Pt(II) and Pd(II) Complexes Modulates Stability and Emission Characteristics: Toward Brighter Versatility

Chemistry – A European Journal, EarlyView.
A new class of cyclometalated metal complexes with pincer luminophores (C^N^O and N^C^O) is reported. They unite high photoluminescence efficiencies in liquid solutions at r.t. with tunable colors across the visible spectrum and convenient synthetic accessibility.

Dual Acid Responses of Stable Luminescent Diphenylpyridylmethyl Radicals With Additional Pyridyl Groups

Chemistry – A European Journal, EarlyView.
To expand the acid‐responsive behavior of diphenylpyridylmethyl stable luminescent radicals, additional pyridyl groups were introduced. Dual acid responsiveness was observed, involving both the newly incorporated pyridyl groups and the PyBTM moieties.

Synthesis and Optical Properties of Diboron Complexes of 1,4‐Anthraquinone Derivatives

Chemistry – A European Journal, EarlyView.
1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.

LUT-based compensation model for OLED degradation

, 2005
A compensation model for blue OLED devices, which is based on an OLED degradation model derived from luminance measurements of OLED devices, has been developed; it reduces degradation effects by monitoring the activity of a set of subpixels and adjusting

A Bio‐Based Chiroptical Overcrowded Alkene From Flavanone: Photoreactivity and Theoretical Investigation

Chemistry – A European Journal, EarlyView.
A sustainable route to photoresponsive molecular systems is achieved using the bio‐based flavanone (‐)‐isolonchocarpin from Tephrosia vogelii. Through McMurry homocoupling and light‐driven 6‐π‐electrocyclization, an overcrowded alkene and a fluorescent O‐heterocyclic phenanthrene are synthesized.

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

Chemistry – A European Journal, EarlyView.
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.
