2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. The different substitution patterns in these heterocycles offer new opportunities for drug discovery and other applications in materials science.Product Details of 6287-82-7

Bis[1]benzothieno[1,4]thiazines: planarity, enhanced redox activity and luminescence by thieno-expansion of phenothiazine was written by Schneeweis, Arno P. W.;Hauer, Simone T.;Reiss, Guido J.;Mueller, Thomas J. J.. And the article was included in Chemistry – A European Journal in 2019.Product Details of 6287-82-7 This article mentions the following:

Two-fold Buchwald-Hartwig aminations selectively furnish three regioisomers of bis[1]benzothieno[1,4]thiazines; x-ray structure analyses and DFT calculations were corroborated for correlation of their electronic properties. All regioisomers outscore the parent compound phenothiazine with respect to a low-lying oxidation potential and reversible redox activity. The anti-anti bis[1]benzothieno[3,2-b:2′,3′-e][1,4]thiazines possess the lowest oxidation potentials in this series and displayed pronounced green luminescence in solution (ΦF≈20%) and in the solid state. Syn-anti regioisomers were only weakly luminescent in solution, but showed aggregation-induced emission enhancement and solid-state luminescence. Most interestingly, x-ray structure analyses revealed that anti-anti derivatives have an amazingly coplanar structure of the pentacyclic anellated 1,4-thiazine system, emphasizing a structural similarity to heteroacenes. The calculated theor. nucleus-independent chem. shifts addnl. suggested that these 8π-electron core systems can be considered as the first electronically unbiased anellated 1,4-thiazines with antiarom. character. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Product Details of 6287-82-7).
