Chen, Xinyu; Zhang, Tong; Han, Yanning; Chen, Qiao; Li, Chengpeng; Xue, Pengchong published an article in 2021. The article was titled 《Multi-responsive fluorescent switches and iodine capture of porous hydrogen-bonded self-assemblies》, and you may find the article in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices.Electric Literature of C14H8Br2 The information in the text is summarized as follows:
A four-armed divinylanthracene derivative was designed and synthesized to construct multifunctional porous self-assemblies. It could form stable supramol. gels, and its fluorescence gradually increased during gelation, exhibiting aggregation-induced emission enhancement. SEM, TEM, BET and mol. simulation suggested that gelators stacked to form one-dimensional porous nanoribbons by multiple hydrogen bonds. The xerogel film might change the fluorescence from green to yellow under force stimuli because of the enhanced π-stacking and recover its fluorescence after solvent annealing. Moreover, fluorescent films acting as sensing materials were applied in the quant. detection of gaseous nitrobenzene and the detection limit reached 1.5 ppb. The sensing film was not sensitive to the gases of common organic solvents. More interestingly, the solids composed of porous nanoribbons might efficiently capture iodine in aqueous and gaseous states, and could be recycled many times. In addition to this study using 9,10-Dibromoanthracene, there are many other studies that have used 9,10-Dibromoanthracene(cas: 523-27-3Electric Literature of C14H8Br2) was used in this study.
9,10-Dibromoanthracene(cas: 523-27-3) is synthesized by the bromination of anthracene. The bromination reaction is carried out at room temperature using carbon tetrachloride as a solvent. Using 80-85% anthracene as raw material, adding bromine to react for half an hour, the yield is 83-88%.Electric Literature of C14H8Br2
