Synthesis and application of 1-(2-methyl-3-benzothienyl)-2-[3-methyl-2-thienyl]perfluorocyclopentene was written by Li, Gang;Liu, Gang;Pu, Shouzhi. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2015.HPLC of Formula: 10243-15-9 This article mentions the following:
A novel unsym. photochromic diarylethene compound 1-(2-methyl-3-benzothienyl)-2-[3-methyl-2-thienyl]perfluorocyclopentene (I) was designed and constructed successfully. Its optoelectronic properties have been discussed systematically, such as photochromic, fluorescence switch, kinetics experiments in hexane solution and PMMA. The consequences showed that this compound exhibited good reversible photochromism. The maxima absorption of compound closed-ring isomer is 468 nm. Upon irradiation with 297 nm UV light, its fluorescence intensity decreased along with the photochromism from open-ring isomers to closed-ring isomers upon irradiation with 297 nm UV light. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9HPLC of Formula: 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. It is also used in the manufacturing of dyes such as thioindigo.HPLC of Formula: 10243-15-9
