Solvent‐Desorption‐Induced Formation of a Long‐Period Polymorph Yielding a High‐Performance Porphyrin‐Based Organic Semiconductor

Advanced Science, EarlyView.
Solvent‐desorption‐induced structural transformation of 5,15‐bisphenyl‐tetrabenzoporphyrin generates a long‐period polymorph, in which the π‐stacking direction rotates by 90° between adjacent layers within the crystal while largely retaining crystallographic integrity.

cis‐Carboxylate Enhancement of Mn(III)‐OH Hydrogen Atom Abstraction through PCET Thermodynamics

Advanced Science, EarlyView.
ABSTRACT Manganese(III)‐hydroxo intermediates are proposed as key hydrogen atom abstraction (HAA) species in manganese‐dependent enzymes, yet how first‐sphere carboxylate ligands control their proton‐coupled electron transfer (PCET) thermodynamics remains poorly understood.

Predicting the Reactivity of Acyclic Silylenes and Germylenes in Hydrogen Activation Using Machine Learning

Advanced Science, EarlyView.
Statistical models for the prediction of the energy profile of H2 activation by silylenes and germylenes were developed. A simple model based on increments of the elements in α‐position enabled robust energy prediction, extrapolation to new structures, and transferability to new tetrylenes and substrates.

Stimulation of OGG1 Enhances Oxidative DNA Damage Repair and Protects Against Acute Liver Failure by Acetaminophen

Advanced Science, EarlyView.
Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...

Linkage Engineering Boosts Battery Performance of Two‐Electron Phenothiazine‐Based Polyamide Cathodes

Advanced Science, EarlyView.
Three phenothiazine‐based polyamides featuring gradually strengthened electron‐withdrawing linkers are developed as high‐voltage cathodes for lithium‐organic batteries. The linker motif serves not only as a structural bridge to suppress solubility, but also as a functional design element that governs optoelectronic properties and electron/ion transport
