A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. 19111-87-6, formula is C18H11Br, Name is 2-Bromotriphenylene. Organobromine compounds have fallen under increased scrutiny for their environmental impact., Name: 2-Bromotriphenylene.
Astier, Raymond;Meyer, Yves research published 《 Transitory absorption bands between 5000 and 8800 A. in aromatic and heterocyclic molecules》, the research content is summarized as follows. Transitory absorption spectra attributable to triplet-triplet transitions were obtained at 3000-8800 A. by a brief, intense light excitation of anthracene, triphenylene, 2-bromotriphenylene, quinoxaline, and anthraquinone in alc. (EtOH:MeOH, 3:1) solution at 113°K. All these mols. had transitory absorption bands in the red part of the spectrum. Intense optical pumping with Xe flash tubes combined with low temperatures gave a large proportion of mols. in a metastable state with a life of a few msec. With anthracene, a triplet state population >95% was measured. The regions of absorption S* ← S(A), fluorescence (F), and phosphorescence T → S(P) are indicated in a figure.
Name: 2-Bromotriphenylene, 2-Bromotriphenylene is a useful research compound. Its molecular formula is C18H11Br and its molecular weight is 307.2 g/mol. The purity is usually 95%.
2-Bromotriphenylene is a brominating agent that has the ability to react with sodium carbonate and emit light. The luminescence of 2-bromotriphenylene can be used as an indicator of the degree of dilution, or how much water is present in a solution. It also emits light when it reacts with chloride ions in a reaction solution. 2-Bromotriphenylene can be used as a polymer matrix to form polymeric films, which are then used as catalysts for organic reactions. The luminescence properties of 2-bromotriphenylene make it suitable for use in functional theory experiments. This chemical compound is relatively low cost, and has been shown to have high yield in catalysis., 19111-87-6.
