Inclusion function of heptakis[6-(alkylthio)-6-deoxy-2-O-sulfo]-β-cyclodextrins, cylindrical surfactants derived from β-cyclodextrin. A study by fluorescent probes was written by Takahashi, Hisao;Irinatsu, Yuichi;Tsujimoto, Munekazu;Kozuka, Seizi;Tagaki, Waichiro. And the article was included in Nippon Kagaku Kaishi in 1987.SDS of cas: 53784-83-1 This article mentions the following:
Title compounds were synthesized by selective modification of β-cyclodextrin (β-CD), as a novel class of anionic cylindrical surfactants. Their inclusion functions were studied in water by using fluorescent probes as the guests. Their binding ability for the neutral probe 1-phenylnaphthalene was more than 10-fold stronger than that of β-CD; it was independent of mol. aggregation of the surfactant monomer. Inclusion occurs at the inside of a hydrophobic cavity undergoing the strong influence of the electrostatic effect of anionic sulfate groups and the effect of the chain length of the alkylthio groups. In the experiment, the researchers used many compounds, for example, Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1SDS of cas: 53784-83-1).
Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.SDS of cas: 53784-83-1
