Efficient synthesis, photochromic properties and application of a new unsymmetrical diarylethene was written by Wang, Renjie;Xia, Hongying;Pu, Shouzhi;Cui, Shiqiang. And the article was included in Key Engineering Materials in 2011.Recommanded Product: 10243-15-9 This article mentions the following:
A new unsym. photochromic diarylethene compound, [1-(2-methyl-5-(3-fluorophenyl)-3-thienyl) 2-(2-methyl-3-benzothienyl)]perfluorocyclopentene (1o), was synthesized and its photochem. properties, such as photochromism and fluorescence in solution as well as in PMMA amorphous film were investigated in detail. The results showed that the compound exhibited remarkable photochromism, changing from colorless to violet after irradiation with 297 nm UV light both in solution and in PMMA film. Finally, using this dithienylethene as recording medium, polarization optical recording was carried out successfully. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Recommanded Product: 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 found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, and sertaconazole, and also BTCP.Recommanded Product: 10243-15-9
