Abstract

The Influence of attaching pendant groups with additional coordinating sites to dibenzo-14-crown-4 upon the response of solvent-polymeric membranes to alkali-metal and alka-line-earth cations and protons has been determined. Marked variation in cation selectivity is noted when -OH, -OCH2CH2OCH3, and -OCH2CO2H groups are attached to the central carbon of the three-carbon bridge in the lonophore.
