The lipophilic diamine-diamide macrocycle 13-hexadecyl-1,4,8,11-tetraazacyclotetradeca-12,14-dione transports Cu2+ ions across a bulk CH2Cl2 membrane from a neutral aq. source phase to an acidic aq. receiving phase. The flow of Cu2+ ions is coupled to a counterflow of protons due to a deprotonation/protonation mechanism of the macrocycle amido groups, assocd. to the Cu2+ incorporation/demetalation process. The pH driven transport process is specific for Cu and its rate is independent of the presence of other metal ions in the source phase.

Abstract
The lipophilic diamine-diamide macrocycle 13-hexadecyl-1,4,8,11-tetraazacyclotetradeca-12,14-dione transports Cu2+ ions across a bulk CH2Cl2 membrane from a neutral aq. source phase to an acidic aq. receiving phase. The flow of Cu2+ ions is coupled to a counterflow of protons due to a deprotonation/protonation mechanism of the macrocycle amido groups, assocd. to the Cu2+ incorporation/demetalation process. The pH driven transport process is specific for Cu and its rate is independent of the presence of other metal ions in the source phase.File in questo prodotto:
