Synthetic Route of C8H8Br2In 2019 ,《Tetrameric (Bi4I16)4- Iodobismuthate Templated by 1,ω-Bis(isoquinoline)alkane cation: structure, photoluminescence and enhanced thermochromism》 was published in Chinese Journal of Structural Chemistry. The article was written by Wang, Penga; Chen, Zhi-Rong; Li, Hao-Hong. The article contains the following contents:
Using 1,1′-bis(isoquinoline)-1,4-phenyldimethylenyl (BIQPM2+) cation as template, a new tetrameric (Bi4I16)4- iodobismuthate-containing hybrid with formula of (BIQPM)2(Bi4I16)•H2O (1), has been prepared under solvothermal conditions. The centrosym. Bi4I164- tetraanion is constructed from four edge-shared slightly distorted BiI6 octahedrons. Due to the presence of larger conjugated system (isoquinoline ring), strong π•••π stacking interactions can be observed Besides, strong I•••I interactions can be monitored and extends the 0-D Bi4I164- cluster to a quasi-1-D chain. The smaller energy gap of 2.13 eV is led by these non-covalent interactions. Its IR emission might be caused by strong charge transfer between anions and cations. Furthermore, the reversible thermochromic behavior with low chromotropic temperature of 80° can be observed, whose mechanism was discussed. In the experiment, the researchers used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Synthetic Route of C8H8Br2)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Most of the natural organobromine compounds are produced by marine organisms , and several brominated metabolites with antibacterial , antitumor , antiviral , and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. Synthetic Route of C8H8Br2 In contrast, terrestrial plants account only for a few bromine-containing compounds.
