Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Otto Billeter or How the Oldest [3,3]-Sigmatropic Rearrangement went to Neuchâtel, Part 2 Otto Billeter oder wie die älteste [3,3]-sigmatrope Umlagerung nach Neuenburg kam: Teil 2

CHIMIA, 2000
The historical survey of the uncatalyzed, thermal rearrangement of thiocyanates into isothiocyanates is continued, starting with a review of Otto Billeter's scientific and social career in Neuchâtel. A specific look is taken at 1925 where Ludwig

Metal–carbene-guided twofold cross-coupling of ethers with chromium catalysis

Nature Communications
Coupling by metal–carbene transfer enables the formation of several different bonds at the carbenoid site, enabling prochiral Csp 3 centers that are fundamental three-dimensional substructures for medicines to be forged with increased efficiency. However,

The Synthesis of NiY Zeolite via the Acid Hydrolysis of Ethyl Silicate and Its Catalytic Performance in the Degradation of Benzyl Phenyl Ethers

Inorganics
The siliceous precursor was hydrolyzed from tetraethylorthosilicate (TEOS) under acidic conditions, followed by the addition of sodium aluminate and sodium hydroxide. Y zeolite was subsequently obtained through hydrothermal crystallization under alkaline

A Nanoparticle‐Integrated Complete Manufacturing Pipeline of Chemically Engineered Exosomes

Advanced Science, EarlyView.
We report a novel manufacture technology of chemically engineered exosomes. The four steps of manufacturing, i.e., biogenesis, loading, isolation, and storage, are integrated by the use of a nanoparticle. The manufacture technology incorporates three innovative components, i.e., a new nano‐bio effect, a new composite nanoparticle, and a new isolation ...
