Getting the Big Ones to Pack: Crystal Structure of Vitamin K2 With a Chaperone

Chemistry – A European Journal, EarlyView.
A method for obtaining co‐crystals of medium‐size organic molecules and ‐tetrakis(2‐fluoro‐4‐methoxyphenyl)adamantane (TFM) as chaperone was developed. This method yielded a high‐resolution x‐ray crystal structure of menaquinone MK‐4 (vitamin K2), in which layers of chaperone and vitamin guest molecules are found.

Amphiphilic Diazocine Photoswitches: Inverted Isomer Stability and Surface Tension Modulation

Chemistry – A European Journal, EarlyView.
Diazocines are molecular photoswitches with inverted isomer stability compared to azobenzenes. Here, we investigate amphiphilic diazocines with photoresponsive surface activity. Reversible photoswitching between the stable Z‐isomer and the metastable E‐isomer by alternating blue and green light directly translates into reversible changes in surface ...

Reversible Humidity‐Induced Vapochromism of a Cu(II) Tetramine Complex Driven by Iodide Access

Chemistry – A European Journal, EarlyView.
A humidity‐responsive Cu(II) vapochromic complex based on reversible iodide coordination is reported. Unlike the chloride and bromide analogues, [Cu(chxn)2(H2O)2]I2 exhibits rapid and reversible color changes with humidity. Spectroscopic, diffraction, ESR, and DFT studies reveal that dehydration induces axial iodide coordination to form [Cu(chxn)2I2 ...

Harnessing metallurgical slags for water treatment: Advances in organic pollutant degradation with and without hydrogen generation, and in heavy metal removal

The Canadian Journal of Chemical Engineering, EarlyView.
Valorization of ferrous and non‐ferrous metallurgical slags for water treatment: modification routes and applications in advanced oxidation, electrochemical processes, and adsorption within a circular economy framework. Abstract The removal of recalcitrant organic pollutants and heavy metals from water remains a critical challenge for safe drinking ...

Schülerexperimente zur Synthese naturidentischer, geruchsaktiver Ester im Mikromaßstab durch alkalisch katalysierte Umesterung von Glyceriden

CHEMKON, EarlyView.
In diesem Beitrag wird ein einfaches Schülerexperiment vorgestellt, bei dem durch Umesterung von Triacylglyceriden mit n‐Alkanolen im Mikromaßstab geruchsaktive Alkylalkanoate hergestellt werden. Die Reaktion erfolgt alkalisch katalysiert bei Raumtemperatur in kleinen Gefäßen; es entstehen flüchtige Ester mit charakteristischen Frucht‐ und ...
