Preparation of poly(quinoxaline-5,8-diyl) derivatives by using zero-valent nickel complexes. Electrical and optical properties and light-emitting diodes was written by Kanbara, T.;Inoue, T.;Sugiyama, K.;Yamamoto, T.. And the article was included in Synthetic Metals in 1995.Application In Synthesis of 5,8-Dibromoquinoxaline This article mentions the following:
Dehalogenation polycondensation of 5,8-dibromoquinoxaline derivatives affords π-conjugated poly(quinoxaline-5,8-diyl) derivatives having high electron-accepting properties, and the polymers are easily converted into elec. conducting materials on chem. and electrochem. reductions The polymers having aromatic substituents show strong fluorescence and are useful materials to make light-emitting diodes. In the experiment, the researchers used many compounds, for example, 5,8-Dibromoquinoxaline (cas: 148231-12-3Application In Synthesis of 5,8-Dibromoquinoxaline).
5,8-Dibromoquinoxaline (cas: 148231-12-3) belongs to pyrazine derivatives. Pyrazine heterocycles and their benzo derivatives possess many interesting properties, including chemical reactivity profiles, and have diverse applications in total synthesis, medicine, chemical biology, materials, dyes, and imaging. Pyrazines are chemical compounds (technically called “methoxypyrazines”) found in grape skin and stems that are responsible for many “green” flavors in wine. Levels of pyrazines are dependent on viticultural practices, climate, and grape variety.Application In Synthesis of 5,8-Dibromoquinoxaline
