Application of 148231-12-3, New Advances in Chemical Research in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 148231-12-3, Name is 5,8-Dibromoquinoxaline, molecular formula is C8H4Br2N2. In a article，once mentioned of 148231-12-3
Dehalogenation polycondensation of 5,8-dibromoquinoxaline derivatives and 2,6-dibromoquinoxaline with zerovalent nickel complex affords a series of pi-conjugated polyquinoxalines with a molecular weight of 6 x 103 to 260 x 103. The polymers are electrochemically reduced (or n-doped) with an E value of -1.75 to -2.35 V vs Ag/Ag+ and converted into electrically conducting materials with a conductivity of 1 x 10-4 to 7 x 10-3 S cm-1 by chemical reduction. Poly(quinoxaline-5,8-diyl)s with aromatic substituents give strong fluorescence with emission peaks at 450-520 nm in solutions as well as in cast films. A light-emitting diode (LED), ITO/polymer/Mg(Ag) (polymer = poly(2,3-diphenylquinoxaline-5,8-diyl)), emits blue-green light (lambda(max) at about 500 nm). Introduction of hole-transporting layers such as vacuum-deposited or spin-coated thin layers of poly(thiophene-2,5-diyl), poly(p-phenylene), and poly(N-vinylcarbazole) between ITO and the light-emitting layer enhances electroluminescence efficiency by about 2 orders of magnitude. Polyquinoxalines have an ionization potential of 5.83 ± 0.11 eV and a band gap of 2.56 ± 0.26 eV.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 148231-12-3, and how the biochemistry of the body works.Application of 148231-12-3
