Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Name: Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin

Cooperative heterodimer formation between per-guadinylated and carboxylated or phosphorylated cyclodextrins in DMSO and DMSO-water studied by NMR spectroscopy and micro-calorimetry was written by Fotiadou, Katerina;Thanassoulas, Angelos;Nounesis, George;Yannakopoulou, Konstantina. And the article was included in Supramolecular Chemistry in 2011.Name: Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin This article mentions the following:

The anionic cyclodextrins (CDs), heptakis[6-(3-thiopropionate)-6-deoxy]-β-CD, heptakis[6-(thio-ethanoate)-6-deoxy]-β-CD and partially phosphorylated 6-(aminoethylphosphate)-6-deoxy-β-CD as triethylammonium salts, bpsp.NHEt3, bpse.NHEt3 and bphos.NHEt3, resp., interacted with the pos. charged picrate salt of heptakis[6-(guanidino)-6-deoxy]-β-CD, bguan.picrate, to form heterodimers as shown by NMR spectroscopic and micro-calorimetric isothermal titration calorimetry (ITC) titrations in solution Association constants, Ka (M-1) in DMSO-d6 and in DMSO-d6-H2O (80/20, volume/volume) were: bguan.picrate/bpsp.NHEt3, 6.4 × 105 and 5.9 × 104; bguan.picrate/bpse.NHEt3, 4.2 × 104 and 1.2 × 104; ITC data in DMSO agreed with those above: bguan.picrate/bpsp.NHEt3, Ka = 4.7 ± 0.1 × 105 M-1, ΔH = – 83.97 kJ mol-1, ΔS = – 173.19 J mol-1K-1; bguan.picrate/bpse.NHEt3, Ka = 2.4 ± 0.2 × 105 M-1, ΔH = – 88.49 kJ mol-1 and ΔS = – 182.27 J mol-1K-1. Heterodimers are highly stable in DMSO and less stable in DMSO-H2O. Multivalency in the interactions is manifested by pos. cooperativity, neg. enthalpy of formation (ΔH) and sizeable neg. entropy (ΔS), in support of the development of well-ordered supramol. structures in solution In the experiment, the researchers used many compounds, for example, Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1Name: Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin).
