Synthesis and Application of 1-[(2-methyl-3-benzothiophene)]-2-[2-methyl-5-(1,3-dioxolane)-3-thienyl]perfluorocyclopentene was written by Fu, Yinglong;Zhou, Lingyao;Fan, Congbin;Pu, Shouzhi. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2015.Electric Literature of C9H7BrS This article mentions the following:
A new unsym. photochromic diarylethene I was synthesized and its photochromic and fluorescence properties were investigated in detail. The results showed this compound exhibited reversible photochromism, undergoing reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light in solution Compound I changed from colorless to pink upon irradiation with 297 nm UV light, in which absorption maxima were observed at 516 nm in acetonitrile. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Electric Literature of C9H7BrS).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.Electric Literature of C9H7BrS
