Chiral Porphyrin Monolayers on Ferromagnetic Thin Films: Ultrafast Spectroscopy of Hybrid Interfaces

Advanced Optical Materials, Volume 14, Issue 33, 4 September 2026.
Chiral porphyrin–oligopeptide monolayers covalently bound to Au‐capped Co/Ni multilayers form surface‐parallel J‐type aggregates and exhibit measurable singlet‐state transient absorption despite monolayer coverage. Femtosecond pump–probe spectroscopy reveals strong excited‐state quenching at the metal interface, yet no long‐lived charge‐transfer ...

Water‐Enabled Ultralong Full‐Color Organic Phosphorescence in Hydrogen‐Bonded Frameworks for 4D Encryption and Bio‐Imaging

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Water‐induced quenching challenges organic RTP materials, but a counter‐intuitive strategy employs HOF to encapsulate carbonyl guests, where water functions as a structural reinforcer. This achieves water‐enhanced ultralong RTP with full‐color emission (blue to deep red), overcoming intracellular quenching for high‐signal cellular imaging, alongside 4D

Research Progress of Room‐Temperature Phosphorescence Materials Based on Reversible Bonding Interactions

Aggregate, Volume 7, Issue 9, September 2026.
This review summarizes the latest progress of RTP materials with self‐healing and shape–memory functions, in which reversible bonding interactions are the key points. With the careful discussions of the typical strategies and representative works, the intrinsic relationship between dynamic bonding interactions and RTP property is well revealed. Finally,

Triplet Acetone Generation by Pseudoperoxidase Activity of Myoglobin: Structural Damage and Quenching

Luminescence, Volume 41, Issue 9, September 2026.
Ferrimyoglobin pseudoperoxidase activity was demonstrated during isobutyraldehyde oxidation, yielding electronically excited triplet acetone and inducing structural damage. Sorbates and 9,10‐dibromoanthracene‐2‐sulfonate exhibited protective effects.

N‐Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions

Chemistry – A European Journal, Volume 32, Issue 33, 1 September 2026.
Acridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.

Physicochemical properties, fermentative profile, microbiological quality, and pathogen contamination of baled silage during long‐term storage

Journal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7454-7463, September 2026.
Abstract BACKGROUND Baled silage is expanding in Mediterranean regions due to climate change and demand for high‐quality forage; therefore, evaluating the effects of long‐term storage on microbiological and fermentative quality is essential. RESULTS In this study, 115 baled silages were sampled from different farms at 30, 60, 90, 180, and 270 days ...
