Novel macrocyclic carriers for proton-coupled liquid membrane transport: Progress report, 1 December 1986-31 July 1987
The objective of our research program is to elucidate the chemical principles which are responsible for the cation selectivity and permeability of liquid membranes containing macrocyclic carriers. A number of new carriers were synthesized, based on the inclusion of triazolo, pyridono, and sulfonamide groups in the principal macrocyclic ring. Many of these show interesting transport characteristics, especially with respect to Li/sup +/, Ag/sup +/, and Cs/sup +/. Hydrophobic crown ethers were successfully incorporated into supported liquid membranes of the flat sheet and hollow fiber types. Hollow fiber transport demonstrated selectivities and permeabilities similar to those observed in the flat sheets.
