Synthesis, properties and optical recording of a novel unsymmetrical photochromic diarylethene was written by Wang, Liqin;Pu, Shouzhi;Yan, Liushui;Cui, Shiqiang. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2011.SDS of cas: 10243-15-9 This article mentions the following:
A new unsym. photochromic diarylethene, 1-(2-methyl-3-benzothienyl)-2-(2-butyl-5-methylol-3-thienyl)perfluorocyclopentene (1a), was synthesized and its photochromism and fluorescence were studied in in solution and in poly(Me methacrylate) (PMMA) amorphous films. Polarization multiplexed image recording was carried out using closed-form of 1a in PMMA film and linearly polarized 633 nm laser diode for recording/readout. The diarylethene can be potentially used as holog. optical recording medium. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9SDS of cas: 10243-15-9).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Benzothiophene is used as starting material for the synthesis of bioactive molecules. The core structure is a part of various pharmaceutical substances and natural products. The different substitution patterns in these heterocycles offer new opportunities for drug discovery and other applications in materials science.SDS of cas: 10243-15-9
