A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 2847-30-5, Name is 2-Methoxy-3-methylpyrazine, molecular formula is C6H8N2O. In an article, author is Yu, You-Jun,once mentioned of 2847-30-5, Application In Synthesis of 2-Methoxy-3-methylpyrazine.
Derivatives based on anthryleno[1,2-b]pyrazine-2,3-dicarbonitrile (DCPA) are used as luminescent materials, to realize near-infrared (NIR) electroluminescence. By functionalizing DCPA with aromatic amine donors, two emitters named DCPA-TPA and DCPA-BBPA are designed and synthesized. Both molecules have large dipole moments owing to the strong intramolecular charge transfer interactions between the amine donors and the DCPA acceptor. Thus, compared with doped films, the emission of neat films of DCPA-TPA and DCPA-BBPA can fully fall into the NIR region (>700 nm) with increasing surrounding polarity by increasing doping ratio. Moreover, the non-doped devices based on DCPA-TPA and DCPA-BBPA provide NIR emission with peaks at 838 and 916 nm, respectively. A maximum radiance of 20707 mW Sr-1 m(-2) was realized for the further optimized device based on DCPA-TPA. This work provides a simple and efficient strategy of molecular design for developing NIR emitting materials.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 2847-30-5, you can contact me at any time and look forward to more communication. Application In Synthesis of 2-Methoxy-3-methylpyrazine.
