Series of Re(I) carbonyls complexes were designed and synthesized to explore the impact of the triimine skeleton and number of methoxy groups attached to aryl substituents on their optoelectronic and thermal properties. The chem. structures of the prepared complexes were confirmed by 1H and 13C NMR spectroscopy, HR-MS, elemental anal., and x-ray measurements. DSC measurements showed that they melted in the range of 198-325°. Some of them form stable mol. glasses with high glass transition temperatures (158-173°). Exptl. obtained optical properties were supported by DFT calculations The UV-Vis spectra display a series of overlapping absorption bands in the range 200-350 nm, and much weaker broad band in the visible spectral region, due to intraligand and charge transfer transitions, resp. All synthesized complexes were emissive in solution and in solid state as powder. Moreover, when applied in diodes, some of them exhibited ability for emission of light under external voltage with maximum of electroluminescence band located at 591-630 nm.
22047-25-2, 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., Computed Properties of 22047-25-2
