The article was titled 《Functionalized ionic porous organic polymers exhibiting high iodine uptake from both the vapor and aqueous medium》, and you may find the article in ACS Applied Materials & Interfaces.Reference of 1,4-Bis(bromomethyl)benzene The information in the text is summarized as follows:
Large-scale generation of radioactive iodine (129I, 131I) in nuclear power plants pose a critical threat in the event of fallout, thus rendering the development of iodine sequestering materials (from both the vapor and aqueous medium) highly pivotal. Herein, the authors report two chem. stable ionic polymers containing multiple binding sites, including Ph rings, imidazolium cations, and bromide anions, which in synergy promote adsorption of iodine/triiodide anions. In brief, exceptional iodine uptake (from the vapor phase) was observed at nuclear fuel reprocessing conditions. Furthermore, the ionic nature propelled removal of >99% of I3- from water within 30 min. Addnl., benchmark uptake capacities, as well as unprecedented selectivity, were observed for I3-anions. The excellent affinity (distribution coefficient, ∼105 mL/g) enabled iodine capture from seawater-spiked samples. Moreover, iodine-loaded compounds showed conductivity (10-4 S/cm, 10-6 S/cm), placing them among the best known conducting porous organic polymers. Lastly, DFT studies unveiled key insights in coherence with the exptl. findings. In the experiment, the researchers used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Reference of 1,4-Bis(bromomethyl)benzene)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. Reference of 1,4-Bis(bromomethyl)benzene Dehydrobromination, Grignard reactions, reductive coupling, Wittig reaction, and several nucleophilic substitution reactions are some of the principal reactions which involve organic bromides.
