Photochromic composite properties and application in optical memory of a diarylethene with benzofuran unit was written by Jing, Shuhong;Cui, Shiqiang;Pu, Shouzhi. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2012.HPLC of Formula: 10243-15-9 This article mentions the following:
A new photochromic diarylethene, 1-[2-methyl-(5-(4- dioxolane)phenyl) -3-thienyl]-2-(2-methyl-3-benzofuran) perfluorocyclopentene (1o), was synthesized and its photochromic and fluorescent properties were investigated. The product has been characterized by elemental analyses, NMR spectrometry, UV/vis spectrophotometry and Fluorescence spectrophotometry. This diarylethene exhibited reversible photochromism and notable fluorescence photoswitches both in solution and in PMMA films, changing from colorless to pink after 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 scaffolds are of great importance due to its increased presence in bioactive molecules. It is also used in the manufacturing of dyes such as thioindigo.HPLC of Formula: 10243-15-9
