Synthesis, Solubilization, and Photophysical Properties of Polyfluorinated Pentacene Dimers

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
The synthesis and photophysical analysis of polyfunctionalized pentacene dimers is described. Polyfluorination is employed to modulate the polarizability and to investigate the effects on the mechanism of singlet fission (SF). ABSTRACT A polyfluorinated pentacene dimer, linked with a 1,3‐diethynylphenylene spacer, was synthesized to investigate the ...

Mechanochemical Dehydrogenative Phenochalcogenazination: A Pronounced Water Effect

ChemSusChem, Volume 19, Issue 12, 26 June 2026.
We report herein the first organic solvent‐free mechanochemical dehydrogenative phenochalcogenazination reaction, with a persulfate salt as a terminal oxidant and wetted silica as a crucial additive. A mechanochemical phenochalcogenazination (X = O, S, Se) of phenols and related compounds in the ball mill is reported.

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

Mechanically Activated Luminescence in Polyurethanes Incorporating Calixarene Mechanophores

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
The conformational flexibility of a calix[4]arene is exploited to obtain a reversible mechanoluminophore featuring a pyrene excimer couple at the upper rim. Stretching a linear polyurethane incorporating such mechanophore results in luminescence color change from yellow–green to blue, consistent with a force‐induced conformational motion of the ...

Phase‐Field Simulation for the Microstructural Evolution of CuPb2F6 During Defluorination

physica status solidi (a), Volume 223, Issue 11, 10 June 2026.
A CALPHAD‐coupled phase‐field model uncovers how discharge rate and nucleation density control Cu nanoparticle formation in CuPb2F6 cathodes. Faster kinetics produce finer particles governed by concentration gradients, enhancing reversible capacity.

Mechanochemical Hydrodeoxygenations

European Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
A silver‐catalyzed mechanochemical hydrodeoxygenation with triethylsilane as reductant allows to convert ketones to the corresponding methylene derivatives in good yields after a short reaction time. Selected examples show that also alcohols, ethers, and sulfoxides can react. In this work, a mechanochemical hydrodeoxygenation (HDO) was developed. Using
