Cryptophane e
WebCryptophane-A, comprised of two cyclotriguaiacylenes joined by three ethylene linkers, is a prototypal organic host molecule that binds reversibly to neutral small molecules via London forces. Of note are trifunctionalized, water-soluble cryptophane-A derivatives, which exhibit exceptional affinity for xenon in aqueous solution. WebSep 4, 2001 · The line widths for cryptophanes A and E are broadened by the exchange of xenon between the cage and tetrachloroethane, the organic solvent used.
