The high-affinity interactions between cis-diols and boric/boronic acid have been widely used as a tool for carbohydrate anal., protein separation and B removal. Here, we report the design and synthesis of cyclodextrin-scaffolded glycopolymers as bifunctional nanosponges for B removal and water treatment for the 1st time. Different glycopolymer nanosponges (GNs) were synthesized from monosaccharides and β-cyclodextrin via a combination of a crosslinking reaction, Fischer glycosylation and a click reaction. Such functional GNs are mesoporous polymer frameworks with cis-diol-containing saccharides immobilized on the surface, which have exhibited selective adsorption behavior towards boric acid depending on the structure of the GNs and the loaded saccharides. The GNs showed remarkable adsorption rates and capacities for an organic dye as a model pollutant in this work. Secondary bonding, such as H bonding and van der Waals forces between the immobilized saccharides and the adsorbates is believed to be responsible for the significantly enhanced adsorption rates and capacities. Such bifunctional materials may exhibit potential applications in seawater desalination and water treatment. In the experiment, the researchers used many compounds, for example, Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1Safety of Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin).
Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Safety of Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin
