In 2022,Zhang, Wei; Luo, Yang; Jia, Meng-Hao; Ni, Xin-Long; Tao, Zhu; Xiao, Chao-Da; Xiao, Xin published an article in Sensors and Actuators, B: Chemical. The title of the article was 《An efficient supramolecular artificial light-harvesting system based on twisted cucurbit[15]uril and cucurbit[10]uril for live cell imaging》.Electric Literature of C14H8Br2 The author mentioned the following in the article:
The construction of highly efficient artificial light-harvesting systems in aqueous solutions is still challenging. Herein, we reported a new light-harvesting system based on the supramol. combination of twisted cucurbit[15]uril (tQ[15]), cucurbit[10]uril (Q[10]), and an anthracene derivative (APy) with aggregation-induced emission (AIE) properties. The Q[n]-based linear supramol. polymer, APy@tQ[15]@Q[10], was constructed through a two-step assembly strategy. Subsequently, a highly efficient artificial light-harvesting system with relatively high antenna effect and energy transfer efficiency was successfully constructed through non-covalent interactions between Rhodamine B (RB, acceptor) and the APy@tQ[15]@Q[10] (donor). The resulting system was compatible with HeLa cells and could be used for live-cell imaging in the red channel. This supramol. assembly strategy has not only produced a highly efficient light-harvesting system but also expands the application of Q[n]s in the biomedical field. After reading the article, we found that the author used 9,10-Dibromoanthracene(cas: 523-27-3Electric Literature of C14H8Br2)
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
