OH-Detected Aromatic Microsolvation of an Organic NO Radical: Halogenation Controls the Solvation Side.
J Phys Chem A

Institute of Physical Chemistry, University of Göttingen, Tammannstrasse 6, 37077 Göttingen, Germany.
The persistent organic radical 2,2,6,6-tetramethylpiperidinyloxyl (TEMPO) protects its NO radical center by four methyl groups. Two of them are arranged tightly (t) on one side of the six-membered puckered heterocycle, and the other two more openly (o) on the other side. It is shown by OH stretching infrared spectroscopy in heated supersonic jet expansions that the hydrogen bond and aromatic ring of a first solvating benzyl alcohol have almost no preference for either side.

The structural response of 1,2-dimyristoyl-glycero-3-phosphatidylcholine (DMPC)/water bilayers to addition and subsequent solvation of a small amphiphilic molecule - an anesthetic benzyl alcohol - was studied by means of solid-state NMR (H NMR, P NMR) spectroscopy and low-angle X-ray diffraction. The sites of binding of this solute molecule within the bilayer were determined - the solute was shown to partition between several sites in the bilayer and the equilibrium was shown to be dynamic and dependent on the level of hydration and temperature. At the same time, it was shown that solubilization of benzyl alcohol reached a solubility limit and was terminated when the ordering profile of DMPC hydrocarbon chains adopted finite limiting values throughout the whole chain.

Propolis, a natural product with remarkable therapeutic potential, has gained attention for its antimicrobial, antioxidant, and anti-inflammatory properties. In this study, propolis samples from Sarıyaprak, Kovanağzı, and Çemikari in Pervari, Siirt province, were analysed comprehensively. The evaluation included wax composition, DPPH and FRAP assays, total phenolic and flavonoid content, and pollen analysis.

Open metal sites are crucial in catalysis. We have used a "loose coordination strategy" (LCS) to preorganize open metal sites in gold cluster catalysts. A gold nanocluster with composition of [Au26(3,4-Me2-Ph-form)9(iPr2-imy)3(Me2S)](BF4)2(iPr2-imy = 1,3-Diisopropylimidazolium tetrafluoroborate, 3,4-Me2-Ph-form = N,N'-Di(3,4-dimethyl-phenyl)formamidine) (Au26) has been obtained by one pot synthesis, i.

The electrochemical oxidation of alcohol molecules has gained significance as a key anode reaction, offering an alternative to the oxygen evolution reaction (OER) for hydrogen (H) production and carbon dioxide (CO) reduction. The (photo)electrochemical oxidation of benzyl alcohol and its derivatives serves as an important model system, not only because benzyl alcohol oxidation is a critical industrial process, but also because it offers valuable insights into electrocatalytic biomass conversion. Tailoring this reaction through electrochemical and photoelectrochemical methods using heterogeneous noble and transition metal electrocatalysts presents a green approach and the potential for uncovering new reaction mechanisms.
