Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

A fluorescence lifetime-based novel method for accurate lipid quantification of BODIPY vital-stained C. elegans

Journal of Lipid Research
Lipid droplets (LDs) are organelles associated with lipid storage and energy metabolism, thus, their morphology and quantity are of significant research interest.

Auf dem Weg zu chromoselektiven Transformationen in biologischen Systemen: Perspektiven und Herausforderungen

Angewandte Chemie, EarlyView.
Die Kontrolle biologischer Systeme mit organischen Chromophoren hat sich zu einer vielversprechenden Strategie entwickelt und findet Anwendung von der chemischen Biologie bis hin zur Medizin. Die Komplexität von In‐vivo‐Systemen lässt sich jedoch nicht mit nur einer einzigen Lichtwellenlänge adäquat abbilden.

Mex-3 RNA-binding family member A limits macrophage ferroptosis-associated injury linked to the SLC7A11/GPX4 pathway in diabetic atherosclerosis. [PDF]

Clin Transl Med
Diabetes reduces macrophage MEX3A and aggravates atherosclerotic plaque instability. MEX3A stabilises Slc7a11 and Gpx4 mRNAs to sustain SLC7A11/GPX4 antioxidant defence. MEX3A deficiency promotes macrophage ferroptosis, lipid peroxidation and mitochondrial injury. Ferrostatin‐1 partially attenuates ferroptotic injury and diabetic plaque destabilisation.

Holographic Photopolymerizable Glass: Enhancing Exposure Sensitivity by Tailoring Photoinitiating Systems Based on BODIPY Dyes

Advanced Photonics Research
The photoinitiating system (PIS) is a key component of holographic materials which needs to be carefully selected and optimized to achieve efficient photopolymerization and, as a result, highly efficient holographic structures.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Stabilization of PUFA‐Rich Mayonnaise Against Lipid Oxidation: A Review of the Last Three Decades of Research

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Mayonnaise, a widely consumed oil‐in‐water emulsion, is highly susceptible to lipid oxidation due to its high content of polyunsaturated fatty acids (PUFAs) and the presence of pro‐oxidant factors such as low pH and iron from egg yolk. Over the past three decades, extensive research has focused on understanding oxidation mechanisms, analytical

T½ Tuning in a Synergistic BODIPY‐Tetrazole Fe(II) Spin‐Crossover‐Photoluminescence System via Co‐Ligand Variation

Chemistry – A European Journal, EarlyView.
We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...

Bioresponsive pseudoGlucosinolates (psGSLs) Release Isothiocyanates (ITCs) in the Presence of Nitroreductases

Chemistry – A European Journal, EarlyView.
This work introduces the concept of pseudoglucosinolates (psGSLs) and reports the synthesis and evaluation of nitroreductase‐responsive psGSLs. These compounds represent a complementary prodrug strategy to natural glucosinolates (GSLs) for the controlled release of isothiocyanates (ITCs), enabling bio‐responsive protein labeling, as demonstrated in ...

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.
