The triphenylamine derivative with a terpyridine-like unit, {4-[p-(N,N-diphenylamino)-phenyl]-2,6-di(pyrazin-2-yl)pyridine}, and its doubly N-methylated salt have been successfully synthesized and characterized. The salt with much enhanced intramol. D-A interaction shows a remarkable bathochromical shift of its absorption bands and a fluorescence quenching effect. And its oxidative electropolymerization film with tunable thickness and non-diffusion controlled redox behavior has also been obtained by cyclic voltammetry on the working ITO electrode. The film possesses an independent dual-wavelength response in visible (400-850 nm) and near-IR (850-2100 nm) spectral regions under different voltages. The low-voltage-controlled electrochromism displays significant color change from pale yellow to dark blue (ΔT% = 78%) with fast response time (6 s for the coloration step and 3 s for the bleaching step), high coloration and bleaching efficiencies (363.7 and 238.5 C-1·cm2) at λmax = 730 nm between -0.2 and + 1.2 V.
Formula: C6H6N2O, 2-Acetylpyrazine has been identified as one of the volatile flavor constituents in popcorn, wheat and rye bread crust.
2-Acetylpyrazine, also known as 1-pyrazinylethanone or fema 3126, belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R’, where R = aryl group and R’=alkyl group. 2-Acetylpyrazine exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 2-acetylpyrazine is primarily located in the cytoplasm. 2-Acetylpyrazine has a bitter, bread crust, and chip taste.
2-acetylpyrazine is a pyrazine that is substituted by an acetyl group at position 2. It has been identified as one of the volatile flavor constituents in popcorn, bread crust, vinegar, and potato snacks. It has a role as a flavouring agent. It is an aromatic ketone and a member of pyrazines.
2-Acetylpyrazine is a nitrogen containing compound that has been used in biological studies. 2-Acetylpyrazine has been shown to have inhibitory properties against the growth of prostate cancer cells and other cell lines. It also inhibits the production of fatty acids and epidermal growth factor, which are important for cellular proliferation. The inhibition is due to the photochemical properties of 2-acetylpyrazine, which cause the formation of reactive species that react with biological molecules. The reactive species may be generated by either a reaction mechanism or a reaction pathway that involve coordination geometry. 2-acetylpyrazine has also been used as a fluorescence probe for fatty acid detection in lipid bilayers and liposomes., 22047-25-2.
