Miao, Xinrui; Cai, Zhengkai; Li, Jinxing; Liu, Liqian; Wu, Juntian; Li, Bang; Ying, Lei; Silly, Fabien; Deng, Wenli; Cao, Yong published their research in ChemPhotoChem in 2021. The article was titled 《Elucidating Halogen-Assisted Self-Assembly Enhanced Mechanochromic Aggregation-Induced Emission》.HPLC of Formula: 591-18-4 The article contains the following contents:
We present a successful strategy to obtain a self-assembled material stabilized by halogen bonding with enhanced mechanochromic aggregation-induced emission (AIE). The meta-bromophenyl-substituted tetraphenylethene fluorophore (m-BrTBE) exhibits an emission which is more red-shifted compared to the phenyl-ring-substituted tetraphenylethene fluorophore (TBE) in film. Remarkably, m-BrTBE mols. self-assemble into uniform ball-like aggregates with high photoluminescence quantum yield up to 85.3%, which indicates that the mol. conformation and intermol. interactions are different from those in the crystalline state. Based on single-crystal anal., scanning tunneling microscopic observations, and theor. calculations, the unusual self-assembly enhanced AIE behavior is attributed to the important effect of meta-bromide substituents which not only form intermol. Br···π halogen bonding and H···Br hydrogen bonding interactions to block nonradiative relaxation pathways effectively but also promote radiative processes. After reading the article, we found that the author used 1-Bromo-3-iodobenzene(cas: 591-18-4HPLC of Formula: 591-18-4)
1-Bromo-3-iodobenzene(cas: 591-18-4) has been used in the preparation of 1-(3′-bromophenyl)-3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodec-1-ene and 1-(3′-bromophenyl)-3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene.HPLC of Formula: 591-18-4 Further, it is involved in the preparation of oxygen-tethered 1,6-enynes.
