Dual‐Mode Thio‐MacMillan Organocatalysts: Stereoselective Diels–Alder Reactions or Sacrificial Self‐Cyclization to N‐Bridged Bicyclic Lactams

open access: yesChemistry – A European Journal, EarlyView.
The study of the Diels–Alder reaction of cinnamaldehyde and cyclopentadiene, catalyzed by chiral imidazolidine‐4‐thiones, led to the discovery of a highly regio‐ and stereoselective Michael‐addition and consecutive ring closure. Here, the imidazolidine‐4‐thione not only catalytically activates cinnamaldehyde but also participates as the nucleophile to ...

When Dihedral Angles Mask Denticity in Molecular Conductance

open access: yesChemPhysChem, EarlyView.
This study tests whether higher molecule–electrode denticity increases conductance in single‐molecule junctions. Using nonequilibrium Green's function technique in conjunction with density functional theory simulations and mechanically controlled break‐junction experiments on a tetradentate N‐heterohexacene, it is found that conductance depends mainly ...

Highly Conductive, Flexible, and Recyclable Phase Change Thermal Management Film

open access: yesEcoEnergy, EarlyView.
This Research Highlight focuses on the work that fabricates flexible, recyclable and leak‐proof phase change film via a nacre‐inspired brick‐and‐mortar strategy of shear‐induced orientation followed by hot pressing, where SEBS/POE dual physical crosslinking network and ordered graphite nanoplatelets enhance thermal conductivity, recyclability, and ...

Phosphorus‐Structured Gel Electrolytes Enable Dual Protection for Thermal Runaway‐Resistant Lithium Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The PD‐VI GPE synthesized via in situ γ‐ray polymerization facilitates formation of a dense F/P‐rich SEI layer, enabling stable Li deposition while suppressing interfacial side reactions. The phosphorus‐containing framework enhances separator thermal stability and effectively mitigates O2 release from cathodes, demonstrating improved safety under the ...
