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, HPLC of Formula: 1575-37-7
Li, YiXiang;Wu, Yong;Qin, ZhengSheng;Wang, Gang;Wu, Yuan;Wang, DongDong;Zhang, YiFan;Wang, XinYe;Wu, ChuanMing;Dong, HuanLi research published 《 Substitution effect on solid parking motif and luminescence of diphenylfuro[2,3-b]quinoxaline isomers》, the research content is summarized as follows. The organic mols. combining light-emitting and charge-transporting property are highly expected. We designed and synthesized a pair of isomers, 2,6-diphenylfuro[2,3-b]quinoxaline (26dPFQ) and 2,7-diphenylfuro[2,3-b]quinoxaline (27dPFQ), and investigated effect of changing substituent position on mol. packing motif, conducting and luminescence feature of resulting materials. In CH2Cl2 solution, both isomers, 26dPFQ and 27dPFQ, emit deep blue light with a wavelength of 422 nm and shows photoluminance quantum yield (PLQY) of 58.9% and 48.7%, resp. In crystal, the 26dPFQ employs H-type packing motif and retains blue florescent emission with low PLQY (10.0%) while 27dPFQ adopts J-aggregated packing motif and shows enhanced green fluorescent emission with a PLQY of 55.0%. The organic light-emitting devices for both emitters show deep blue emission, the EL peak at 410 nm for 26dPFQ and 424 nm for 27dPFQ, and resp. presents the maximum EQE of 1.2% and 1.0%. The 26dPFQ shows better charge transport capability over 27dPFQ. Our results suggested 2,6-substitution on furo[2,3-b]quinoxaline core are expected to afford such dual functional materials.
1575-37-7, 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., HPLC of Formula: 1575-37-7
