Synthesis, properties and application in optical memory of a new photochromic diarylethene was written by Liu, Ming;Li, Wei;Pu, Shouzhi;Liu, Gang;Cui, Shiqiang. And the article was included in Key Engineering Materials in 2011.Category: benzothiophene This article mentions the following:
A new photochromic diarylethene compound, 1-[2-methyl-3-benzothiophene]-2-[5-(3-chlorobenzene)-2-methyl-3-thienyl]perfluorocyclopentene, was synthesized and its photochromism and photo-induced anisotropy was investigated. It showed good photochromism and functioned as an effective fluorescent photoswitch in solution In hexane, the open ring isomer of the diarylethene exhibited relatively strong fluorescence at 417 nm when excited at 315 nm. In PMMA film, the open ring form of diarylethene also showed good photochromism. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Category: benzothiophene).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.Category: benzothiophene
