One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine. 1575-37-7, formula is C6H7BrN2, Name is 4-Bromobenzene-1,2-diamine, Formula: C6H7BrN2
Dusold, Carolin;Haines, Philipp;Platzer, Benedikt;Guldi, Dirk M.;Hirsch, Andreas research published 《 Helically and Linearly Fused Rylenediimide-Hexabenzocoronenes》, the research content is summarized as follows. Perylene- as well as naphthalenediimides were fused to hexabenzocoronenes (HBCs) at their imide position to realize highly π-extended donor-acceptor (D-A)-hybrids. Successful isomer separation in the first step was decisive to guarantee a straightforward synthetic sequence. Hexaphenylbenzenes as precursors were accessed via Diels-Alder reactions and reacted in a Scholl oxidation to yield the resp. HBC derivatives The fully conjugated benzimidazole linker, which separates the electron donating HBC from the electron accepting rylenediimide, enabled the formation of either a linear or a helical configuration. Largely different chem., phys., and optoelec. characteristics were noted for the two configurations. What stood out was their aggregation and their excited state deactivation depending on the solvent polarity. Results from global anal. of the femtosecond transient absorption data corroborated the formation of a charge-transfer (CT) state that is stabilized in the helically fused configuration relative to the linear analog. However, a comparison with spectroelectrochem. experiments failed to disclose evidence for a charge-separated (CS) state.
Formula: C6H7BrN2, 4-Bromo-1,2-diaminobenzene can be obtained from 1,2-diaminobenzene via acetylation followed by bromination and alkaline hydrolysis.
4-Bromobenzene-1,2-diamine, also known as 4-Bromobenzene-1,2-diamine, is a useful research compound. Its molecular formula is C6H7BrN2 and its molecular weight is 187.04 g/mol. The purity is usually 95%.
4-Bromo-1,2-diaminobenzene is a dye that is used in diagnostic
procedures to detect the presence of amide groups. 4-Bromo-1,2-diaminobenzene can be used as an inhibitor for cationic polymerization reactions. It also has tuberculostatic activity and inhibits the growth of Mycobacterium tuberculosis. This compound reacts with aniline to form a benzimidazole derivative that contains a reactive amine group. The reaction between this amine group and different electrophiles generates benzimidazole compounds with different properties that are useful in nucleophilic attack reactions. The reaction between 4-bromo-1,2-diaminobenzene and methyl ethyl sulfide produces a luminescent probe that can be used to detect hydrogen bonds., 1575-37-7.
