Water‐Catalytic Deconstructive and Proton Transfer Cyclopropanation of Sulfoxonium Ylide with Olefin

Advanced Science, EarlyView.
Water‐catalytic deconstructive and proton transfer cyclopropanation of sulfoxonium ylide with olefin is developed through a sequential water‐mediated ring‐closing/opening reaction. This atom‐economical, environmentally friendly methodology offers easy access to a range of cyclopropyl ketones with moderate to good yields.

Stable Pincer Gold(III)‐TADF Emitters with Extended Donor–Acceptor Separation for Efficient Vacuum‐Deposited OLEDs with Operational Lifetime (LT95) up to 3831 h at 1000 cd m−2

Advanced Science, EarlyView.
Novel pincer gold(III)‐TADF (thermally activated delayed fluorescence) emitters with extended π‐distances exhibit small singlet‐triplet energy gaps (ΔEST), efficient reverse intersystem crossing (RISC), enhanced radiative decay rates and improved excitons utilization, leading to efficient electroluminescence.

Isotope‐Enriched Cubic Boron Arsenide with Ultrahigh Thermal Conductivity

Advanced Science, EarlyView.
The high‐quality isotope‐enriched cubic boron arsenide crystals that enhance the thermal conductivity of c‐BAs are synthesized and measured at a room temperature thermal conductivity of 1500 W m−1 K−1 for the c‐11BAs. This value is the highest thermal conductivity among known semiconductor materials.

Dynamic Molecular Cocrystals with Alkyl Chain Dependent Thermosalient Phase Transitions

Advanced Science, EarlyView.
A series of cocrystals containing 5‐fluorocytosine and fatty acids with varying alkyl chain lengths are synthesized, demonstrating a systematic modulation of thermosalient phase transition temperatures across a broad range (≈100 K). This study reveals a linear correlation between interlayer hydrophobic interactions and transition temperatures, offering
