2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Name: 2,3-Dibromobenzo[b]thiophene

Characteristic Structures and Photophysical Properties of Nine-Coordinate Europium(III) Complexes with Tandem-Connected Tridentate Phosphane Oxide Ligands was written by Miyata, Kohei;Hasegawa, Yasuchika;Kuramochi, Yusuke;Nakagawa, Tetsuya;Yokoo, Toshiaki;Kawai, Tsuyoshi. And the article was included in European Journal of Inorganic Chemistry in 2009.Name: 2,3-Dibromobenzo[b]thiophene This article mentions the following:

Structures and photophys. properties of three f-block metal complexes with tandem-connected tridentate phosphine oxide ligands, {bis[o-(diphenylphosphoryl)phenyl]phenylphosphine oxide}tris(hexafluoroacetylacetonato)europium(III) [Eu(hfa)3(DPPPO)], {bis[o-(diphenylphosphoryl)pyridyl]phenylphosphine oxide}tris(hexafluoroacetylacetonato)europium(III) [Eu(hfa)3(DPPYPO)] and {bis[o-(diphenylphosphoryl)benzothienyl]phenylphosphine oxide}tris(hexafluoroacetylacetonato)europium(III) [Eu(hfa)3(DPBTPO)], are reported. The coordination geometries of Eu(hfa)3(DPPPO) and Eu(hfa)3(DPBTPO) provide characteristic distorted, capped square antiprism structures with nine-coordinate oxygen atoms. The emission properties related to the electronic transition were characterized by the emission spectra, the emission quantum yields, the emission lifetimes, and the radiative and non-radiative rate constants EuIII complexes with tridentate phosphine oxide ligands offer relatively high emission quantum yields (> 60% in [D6]acetone) due to their low-sym. and low-frequency vibrational structures. The elec. dipole transition intensities in the emission spectra depend on the chem. structures of tridentate phosphine oxides. The characteristic photophys. properties of polyhedral f-block metal complexes, nine-coordinate EuIII complexes with tridentate phosphine oxide, are demonstrated for the first time.

In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Name: 2,3-Dibromobenzo[b]thiophene).
