(NH4)2[Tc2O2(S2O7)4]: An Unexpected Technetium(V)‐Sulfate From the Reaction of (NH4)(TcO4) With SO3

open access: yesChemistry – A European Journal, EarlyView.
The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.

Denaturation of Water in Alkaline Melts

open access: yesChemistry – A European Journal, EarlyView.
Vapor pressure measurements and ab initio molecular‐dynamics simulations reveal that in ultra‐alkaline media with base concentrations up to 70 mol L−1, the activity of water is dramatically reduced by strong bonding interactions. These disrupt traditional hydrogen bonding patterns, alter vapor‐liquid equilibria, and significantly change molecular ...

Bifunctional Molecular Switches in Fused Diarylethene–Rhodamine Systems

open access: yesChemPhotoChem, EarlyView.
Spectroscopic and time‐dependent density‐functional theory studies show that these novel rhodamine‐based diarylethene (DAE) compounds display intense UV absorption, undergo reversible two‐step protonation involving triazole and rhodamine units, and respond selectively to acid, base, and metal ions.
