“…Besides nitrobenzene and NPOE, DClE belongs to the often-studied systems by voltammetry at ITIES. One extraction study was done with the solvent, aimed at practical separations of 137 Cs from acidic solutions by cobalt bis(dicarbollides) . More hydrophobic anion BBr 6 - instead of B - had to be used, and the practical selectivities had been shown to be very similar to the nitrobenzene solvent.…”

Thermodynamic standard Gibbs energies of transfer of alkali metal cations related to Cs+ cation [DeltatG degrees*,(Cs+)-[DeltatG degrees*,(M+)] between several mutually saturated solvents of the type water-solvent were calculated from determined extraction exchange constants Kexch degrees,*(Cs+/M+). The used liquid-liquid extraction method with radioactive tracing by 137Cs permits attaining higher precision of the values as compared to the methods used up to now. The data for o-nitrophenyloctyl ether, 1,2-dichloroethane, and 1-octanol were compared with literature sources and recommended absolute values of DeltatG degrees,*M+) are reported. For dissociating solvents, the dependences of [DeltatG degrees,*(Cs+) - [DeltatG degrees,*(M+)] on Gibbs energy of hydration of an ion, DeltaGhydr degrees are straight lines either for four cations Cs+, Rb+, K+, and Na+ (nitrosolvents) or for three cations Cs+, Rb+, and K+ (1,2-dichloroethane and 1-octanol). The hydration of Na+ and still more of Li+ in the water-saturated organic phase is apparent from the results. This manifests for high-water-content equilibrium 1-octanol even in a reversal of the values [i.e., DeltatG degrees*,(Li+) being more negative than DeltatG degrees,*(Na+)], although for Cs+, Rb+, and K+, the general trend is conserved. Water-saturated 1-octanol is thus slightly less basic than water, but the overall selectivity is very low. For one studied nondissociating solvent, dioctyl sebacate, the trend of the dependences of log Kexch degrees,*(CsB/M+) on DeltaGhydr degrees is similar to that of Kexch degrees,*(Cs+/M+) for polar solvents, but different for different anions B, thus reflecting ion association in the organic phase.

“…23 Moreover, [ 1 ] − , which can cross through synthetic lipid membranes without disrupting membrane integrity, 24 displays low toxicity in vitro 15,16 and in vivo 16,25 and high uptake by relevant cancer cells, 15,26 accumulating in vitro within the nuclei of living cells. 16 Additionally, the anionic [M(C 2 B 9 H 11 ) 2 ] − clusters can be modified at the different vertexes by halogenation, 27–29 and are responsible for additional physicochemical properties. 10,29,30 Recently, amphiphilic inorganic anionic [ 1 ] − clusters have been proposed to stabilize oil-in-water nano-emulsions of poorly water soluble drugs.…”
