Reversible light-driven magnetic switching of salen cobalt complex was written by Wan, Song;Li, Mengqi;Zhang, Zhipeng;Xi, Hancheng;Yang, Hong;Luo, Qianfu;Zhu, Wei-Hong. And the article was included in Science China: Chemistry in 2020.Application of 10243-15-9 This article mentions the following:

Spin-crossover (SCO) metal complexes are expected to be widely used in data storage materials, display devices and sensors. Although a lot of spin-crossover photoswitches have been developed, the reversible photomodulation cases that work at room temperature are limited. Herein, a novel cobalt complex o-1-Co(II) wherein the salen unit bridges with bis-diarylethene has been designed as switch to construct “off-on” logic operation at room temperature The complex o-1-Co(II) displays an abrupt, reversible and hysteretic spin crossover (T1/2↓=166 K, T1/2←=177 K, and ΔT1/2=11 K) between the high-spin (HS) and low-spin (LS) states. Meanwhile, photocyclization of o-1-Co(II) with UV light produces a photoresponsive closed form c-1-Co(II), which always stays at low-spin without SCO at all. Moreover, the magnetic switching of the complex can also be achieved with redox reactions between Co(II) and Co(III). In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Application of 10243-15-9).

3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) 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.Application of 10243-15-9

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 Eu^III 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 Eu^III complexes with tridentate phosphine oxide, are demonstrated for the first time.

The sulfoxides benzo[b]naphtho-[1,2,d]thiophene S-oxide, benzo[b]naphtho[2,1,d]thiophene S-oxide, benzo[b]phenanthro[9,10-d]thiophene S-oxide, dinaphtho[2,1-b:1′,2′-d]thiophene S-oxide, and dinaphtho[1,2-b:2′,1′-d]thiophene S-oxide all absorb light at longer wavelengths than DBTO. To determine if these sulfoxides could be used to generate O(³P), quantum yield studies, product studies, and computational anal. were performed. Quantum yields for the deoxygenation were up to 3 times larger for these sulfoxides compared to DBTO. However, oxidation of the solvent by these sulfoxides resulted in different ratios of oxidized products compared to DBTO, which suggested a change in deoxygenation mechanism. D. functional calculations revealed a much larger singlet-triplet gap for the larger sulfoxides compared to DBTO. This led to the conclusion that the examined sulfoxides could undergo deoxygenation by two different mechanisms. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7HPLC of Formula: 6287-82-7).
