And the article was included in Organic Letters in 2014.Computed Properties of C5H3BrOS This article mentions the following:
A bicyclo-type cage-shaped compound I [R = hexyl] consisting of three sexithiophenes was successfully synthesized and characterized by NMR, HRMS, and X-ray crystallog. anal. The strained cage architecture was reflected in the blue-shifted absorption spectrum relative to its linear analog. Intramol. interaction between three-dimensionally fixed sexithiophenes was suggested by electrochem. anal. In the experiment, the researchers used many compounds, for example, 5-Bromothiophene-3-carbaldehyde (cas: 18791-79-2Computed Properties of C5H3BrOS).
5-Bromothiophene-3-carbaldehyde (cas: 18791-79-2) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Computed Properties of C5H3BrOS
