Synthesis and characterization of unsymmetrical diarylethene based on phenylpentane was written by Zhang, Xiaodong;Wei, Shasha;Pu, Shouzhi. And the article was included in Applied Mechanics and Materials in 2015.Quality Control of 3-Bromo-2-methylbenzo[b]thiophene This article mentions the following:
An unsym. photochromic diarylethene, 1-[2-methyl-3-benzothiophene]-2-[2-methyl-5-(4-pentylphenyl)-3-thienyl]perfluorocyclopentene, has been synthesized, and its properties including photochromism and fluorescence have been investigated. The results showed that this compound undergo reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light in solution In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Quality Control of 3-Bromo-2-methylbenzo[b]thiophene).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Benzothiophene scaffolds are of great importance due to its increased presence in bioactive molecules. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Quality Control of 3-Bromo-2-methylbenzo[b]thiophene
