Wang, Yunsheng; Yang, Jie; Fang, Manman; Gong, Yanxiang; Ren, Jia; Tu, Liangjing; Tang, Ben Zhong; Li, Zhen published an article in 2021. The article was titled 《New Phenothiazine Derivatives That Exhibit Photoinduced Room-Temperature Phosphorescence》, and you may find the article in Advanced Functional Materials.Electric Literature of C6H4BrI The information in the text is summarized as follows:
The research of purely organic room-temperature phosphorescence (RTP) materials with stimulus response characteristic has drawn increasing attention for their broad application prospects. However, these kinds of materials are really scarce now, especially for those with efficient RTP emissions, which have largely limited their practical applications. Here, an all-around-type player in the field of photoinduced phosphorescence material appears, whose RTP efficiency can increase from near 0 to 22% after continuous UV irradiation Correspondingly, the UV-written patterns based on them can be clearly observed by the naked eye in daytime or even under sunlight. Moreover, these materials are found to show excellent photostability, and the strong RTP emission can still be observed after repeated activation for more than 50 times. The high RTP efficiency and good photostability make these photoinduced RTP materials exhibit an attractive prospect for potential applications in many fields, including leak test, microcrack detection, programmable information storage, and encryption. After reading the article, we found that the author used 1-Bromo-4-iodobenzene(cas: 589-87-7Electric Literature of C6H4BrI)
1-Bromo-4-iodobenzene(cas: 589-87-7) is mainly used as the OLED pharmaceutical intermediate, as reagent for in situ desilylation and coupling of silylated alkynes, as substrate in copper-free Sonogashira coupling in aqueous acetone..Electric Literature of C6H4BrI It is also used in synthesis of β,β,dibromostyrenes, as starting reagent in the total syntheses of ent-conduramine A and ent-7-deoxypancratistatin (alkaloids)
