Mechanistic Insights Into Luminol Chemiexcitation: The Role of the Amide Carbonyls
Chemistry – A European Journal, EarlyView.By means of quantum‐chemical calculations, we demonstrate that the 1,2‐dioxin ring forms following nitrogen release from parent luminol. We also identify alkoxide groups derived from the amide carbonyls of luminol as key enhancers of the chemiexcitation yield.

MoleculesNumerous compounds that are scavengers of hydroxyl radicals (•OH) in Fenton systems have low solubility in water. Therefore, they are dissolved in organic solvents to reach suitable concentrations in the reaction milieu of the Fenton system.

Thermodynamics of metal ion cryptates and cryptand 222 in dipolar aprotic solvents.
, 1985 Thermodynamic parameters of transfer of single-ions from water to nitromethane are obtained using the Ph4AsPh4B convention suggested by Parker. Enthalpies of complexing of alkali-metal and silver cations with cryptand 222 in N,N-dimethylformamide ...

Crystallization‐Induced Emission Enhancements of Hybrid Butenolide‐Diphenylethenes
Chemistry – A European Journal, EarlyView.Hybrid butenolide‐diphenylethene fluorophores show crystallization‐induced emission enhancement (CIEE), with substituents tuning solid‐state quantum yields up to 50%. One derivative, BuCM, displays dual‐state emissions (DSE), making this compact scaffold a promising platform for CIEE/DSE‐active fluorophores.

Foldamers With Two Distinct Helical Motifs Controlled by Solvent
Chemistry – A European Journal, EarlyView.Alternating o‐phenylene and 2,3‐pyrazinylene oligomers were synthesized and their conformational behavior studied by NMR spectroscopy, x‐ray crystallography, and DFT calculations. They fold into well‐defined helices, but, remarkably, the folding motif depends on solvent: a compact helix in chloroform, but a much longer extended helix in acetone ...
