The article was titled 《Rewritable optical data storage based on mechanochromic fluorescence materials with aggregation-induced emission》, and you may find the article in Dyes and Pigments.Category: thiazole The information in the text is summarized as follows:
In this work, the synthesis and aggregation-induced emission (AIE) properties of a new mol. system are reported. This system composes of three positional isomers, which are fabricated by attaching a methoxy group in different locations. The isomeric effects on the AIE properties as well as the intramol. charge transfer (ICT) processes were studied. Addnl. the new isomers exhibit mechanochromic fluorescence (MCF). Among the three isomers, (E)-2-(((6-chlorobenzo[d]thiazol-2-yl)imino)methyl)-5-methoxyphenol (CHM3) exhibits the most remarkable MCF performance with emission that decreases in intensity and red-shifts in wavelength under mech. stimuli. The emission changes are caused by crystalline-amorphous transition as verified by Powder X-ray diffraction (PXRD) anal. The mechano-induced state can be easily recovered through a recrystallization process, which can be activated by solvent fumigation or solvent immersion. Furthermore, the switching between two emission states shows nice reversibility. Based on the MCF material with high fatigue resistance, a new type of rewritable optical data storage (ODS) is developed. Binary data, comprised of “”0″” and “”1″” state, can be matched well with the two emission states, resp. The data could thus be written or erased on the ODS device, demonstrating feasibility and practicability. In the experiment, the researchers used many compounds, for example, 6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9Category: thiazole)
6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9) belongs to thiazoles. Thiazoles are a class of five-membered rings containing nitrogen and sulfur with excellent antitumor, antiviral and antibiotic activities.Category: thiazoleThe thiazole ring has been identified as a central feature of numerous natural products, perhaps the most famous example of which is epothilone.
