Mechanofluorochromism (MFC) of Donor–π–Acceptor (D–π–A)‐Type Fluorescent Dyes

The Chemical Record, EarlyView.
Mechanofluorochromism (MFC) is a photophysical phenomenon that induces changes in fluorescent colors as well as colors of organic fluorescent dyes in the solid‐state by external mechanical stimuli. In this Personal Account, we offer an insight into the mechanism for the expression of MFC and present a direction in the molecular design toward creating D–

Synthesis and Characterization of a Cerium(IV) Coordination Polymer Containing Isonicotinic Acid Zwitterions

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The new coordination polymer [Ce4O2(OH)2(NO3)2(C6H5NO2)8](NO3)8 is reported. It was discovered during a ligand screening experiment. Its crystallization was studied in situ via powder X‐ray diffraction and X‐ray absorption near‐edge structure spectroscopy.

Pyrene‐Conjugated, 2‐Pyridinecarboxaldehyde Derivatives as N‐Terminus‐Specific Tags for MALDI‐ and LALDI‐MS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Background Proteolytic processing is a fundamental post‐translational modification. Liquid chromatography–tandem mass spectrometry (LC–MS/MS) workflows are powerful for degradomic analyses but inherently sacrifice spatial information, a critical aspect for investigating biological systems such as aberrant extracellular matrix remodeling and ...
